Arrogance and hubris. Soviet Radioelectronic combat was a serious threat in the 80s and the RFA didn't abolish EW for 15 years like the US Army did. The US Military decided that precision weapons were the solution in 1970s and assumed that nobody could practically jam them after 1990 so basically the US stopped developing other guidance systems for a few decades. And hasn't managed to build/field the user hardware for anti-jam after eventually, after long delays, deploying M-code on the sats. But hey, it worked fine against 3rd world insurgents and terrorists, and we would never be fighting a competent military backed by a large industrialized country, so why spend the money?
@@dtrain1634 in this war? Sure. But don't draw comparisons from Ukraine to a potential war with US involvement. Even in a contested airspace, HARMs are a threat to any EM emitter.

It's way more convenient to use a map on your smartphone even without any navigation. You get multiple layers with instant switch, search, endless coverage, multiple zoom levels, quick measuring tools, marking tools, etc. An equivalent with paper maps is having a navigator guy with you with a backpack full of maps and a map tablet with physical tools. And even then you get old data and it's very hard to collate multiple sources on the fly

@@user-zu2fj5qc5v logically 3 is enough, factually 9 is needed to get constantly accurate positioning. you can try it yourself: track cars for 24/7, compare the acuracy based on the number of satellites received.
@@ViceCoin, from what I hear, that's the direction everyone is headed. Starlink is just the beginning. Drone-type craft will proliferate extremely-low earth orbit and provide distributed communications support.
You see, when the missile gets close, the Russians press X at the right time to affect a dodge roll and the most cunning Russians can leave it until the last second, then do a parry with their tactical shovel.
Fun fact, you actually need 4 satellite signals... time is also a variable. for more accurate and cancelling signal propagation interferences, 6-7 is required for google map level navigation. if you are fast moving missile, more satellites signals are required to remove doppler effects
with 1 sat your accuracy is an infinite sphere, with 2 sats your accuracy is an infinite disc, with 3 sats your accuracy is an infinite line, with 4 sats your accuracy is a point. I'm guessing you ideally want a few more than that in case some of the signals are not getting through at any given time due with clouds, obstacles, etc..
@@shadmansudipto7287 Only if you have a synchronized super-accurate clock, if not you need to also compute the clock as variable. This means you have a 4 unknowns so you need at least 4 equations to solve it, generally speaking.
EW isn't something Russians have abolished. Hell, understanding the physics behind information transfer is what Russians are adept to dealing with even in nuclear war, so i am really surprised USA didn't include anything to deal with the electronic warfare in their top of the line guided bombs. Unless they were really only meant to deal with countries who don't have EW capabilities.
The Raytheons and LMs only do the minimal work required to fulfill the contracts. If they know a GPS receiver with no serious anti-jamming protection will pass then that's what they are going to sell.
We don’t know that Ukraine actually gets all the bells and whistles in the systems. Perhaps they do perhaps they don’t and as with anything in the electronics or spectrums it’s kept secret.
The Russian-Ukraine war is not a good showcase of American made weapons, as such they’re not good showcases of western weapons over all which are to an extent designed with the American army in mind. IE the EU nation would be fighting a 3rd world country without the US and they won’t need the anti jamming capability. Or they’re fighting the Russians, which will mean the Americans are involved. As such American air power is heavily factored in, as well as their SEAD capabilities. These jammers would not survive long in the way they’re currently employed in that threat environment and we would more likely see sporadic jamming of focused areas of the front to cover big pushes. Don’t forget the 2 most potent air forces in the world both belong to the USA lol.
I'm a kind of guy who is more on the "cautious" side of personality. I really really love fool-proof and rugged things. Those magnetic rock formations on the earth, all sorts of gyroscopic navigation and celestial navigation really really impressed me. You can't jam a wire-guided AT missile, you can't jam the location of sun either. It seems to be that due to historical and geopolitical reasons, the Russian military tends to think a design thing in my way rather than the "cool" way. For goodness sake, the jam everything so hard that they jam themselves too, just to make sure that their enemy doesn't have the advantage either 😂
They did not forget how to determine one's location and the target's location, how to determine the direction of artillery guns in traverse and elevation, how to plan, organize and execute the operation of the elements of the fire support system with satisfactory low error level and time consumption, using analogue methods.
There are solutions for this problem. Many aircraft like a B-52 B2 will carry a star tracker accurate to 180m or so. Digital image scene correlation works so does ground mappingradar.
Russian krasnopol shell uses diferent aproach. No gps signal, itis guided by laser marking from a drone. So while they saturate area with jamming, they continue to operate with impunity
The Airforce spent money on home-on-GPS-jammer seekers in 2014. This certainly seems like a pretty straight forward application. In the last couple of months the US Air Force is spending a modest amount of money to actually get these built. I am surprised this weapon isn’t already in the US inventory.
They probably are - they probably sent the "old" stuff to Ukraine and kept the new stuff for themselves. I mean, they're sending F-16s, not F-35s, right?
The United States wasted its money and that of much of the western world in Afghanistan for No real result. This a whole range of weapon systems didn’t get the upgrades they needed. For instance the stinger missile is being jammed by DIRCM. this was all predicted in their ass Solutions but as I said the money went into Afghanistan and fixing the soldiers injuries as much as they could be fixed
Antennas have broad beams an modest gain. But even simple antennas have very sharp and deep nulls. The most effective countermeasure is to point a pattern null at the jammer.
During your presentation, I had visions of myriads of ‘air tags’ being dispensed in flight. Find my keys, find my dog, find my stolen trailer. GNNS Chaff.
I am a radio frequency and network engineer, at least I was in my past. I worked in the field, and I have encountered many things that stop radio signals and interact with them in unexpected ways. Pine trees, for example, they may as well be made of copper. For some reason nothing can penetrate pine trees. If you don't want to get hit by a GPS guided bomb, hide in a coniferous forest lololol
@@Mountain_bonker yeah, it's extremely interesting to think about how radio signals propagate, there's like an invisible world that we are surrounded by at all times. and I agree with you, there's going to be a use for the American minute man once again. Disrupting radio transmission would be an extremely effective way to stop the occupying forces from communicating or using tools against you that require RF signals. Another good rule of thumb when thinking about signals, 30 feet of elevation, that's usually how high you need to get above the ground in order to receive from cell towers on the horizon, any kind of dip in the terrain is a dead zone.
@@OleDiaBole That's what I would have thought, too. pine trees are worse than concrete walls. zero penetration, even using lower frequencies that tend to have better penetration capabilities.
i mean most "modern" southern italian are descendent of mostly classical greeks settelers and some italics people.. (bruti, samnites, latins etc etc) only in recent centuries there was an influx of albanian (who the albians actually are is another issue) and a small minority of Normans there was some sprinkle of iberians and arabs but even if the spaniard owned the land for a while they didn't promote colonization plans of any kind.. most northern italian will have more celtic and german traits given the amount of germanic people that settled there in the late antiquity.. Also is important to notice that by the roman reconquista of Italy (VI-VII century) the population of the entire peninsula dropped below 1ml. That factor alone made the successive migrations of germanic people more influential on the population mix.
One solution I have considered lately is AI driven navigation. One with the ability to keep track of changes of direction and terrain recognition. The fire control technician would provide the drone with a three dimensional map to the target with accurate terrain and structure information of the possible routes. It could use the stars to help navigation but would not be necessary. Once released no amount of signal jamming or spoofing can deter it from accurate weapon delivery.
As a former soldier, every now and then I find my graduation picture from basic training. There I am with my fellow soldiers. Our faces look more like boys and barely young men. It is a sobering thought that it is these young men we may have to send them to war. Enjoy your tech analysis and briefing. They remind me how our battlefield have become more deadly than it was for me 40 years ago.
The reason why INS based weapon systems include GPS is because relative to the INS, GPS receiver is quite small and cheap. It augments the INS system by providing up to date position information, allowing the INS to correct/reset the accumulated drift. For the weapon itself, outside of shielding/directional antennas, one of the best solutions to jamming is actually speed. Since INS drift is a function of time, the faster you go, the less time you spend within range of the jamming systems. When you get up to cruise missile speeds, 20-30 mile effective range of jammers, is small enough to where rather cheap and small(yet ITAR controlled) sensors can achieve a couple meter accuracy. The other solution to jamming is image recognition for terminal guidance. Using IR sensors and AI image recognition will allow target detection/tracking easily at hundreds of meters. That VASTLY decreases the required INS accuracy, while also allowing for the tracking of moving targets. INS accuracy could open up into the hundreds of meters! For the battlespace, the solution to jamming is relatively small long endurance UAV's with directional antennas, and some radio hardware. They'd work in sets of 3 or more to triangulate the jammers. Passing the targeting data to many various ground/air weapon systems. Think of it as a counter artillery for jamming. I wouldn't be surprised if In future war, the poor soldiers who get assigned to the units who deploy jamming equipment, will having some of the shortest life expectancies on the battlefield. I'd bet a good bit of money that whatever agency is operating the USA's ginormous SIGINT satellites, knows every single time, when a jammer is powered up.
This has been discussed many times in the public domain. Both sides have drones that home in on jammers & radars. Ukraine also has HARM missiles specifically designed to counter these kinds of threats.
The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
This is the best prospective answer to the jamming problem. Otis could try to integrate the quotient of the vector matrix of the positions that we're over that of the positions we are not. Then ffsletmein4321 and signiore A could claim the Fields Medal and Otis himself the Peace Nobel Prize. Hilariously exceptional comment this one above.
The claim that for a JDAM a second without GPS adds a metre to the CEP is defintely wrong. A JDAM without GPS to correct it's internal INS has a CEP of 30 metres for a flight time of 100 seconds
I can easily see this being the case for longer range JDAM-ER which as wings and can be prone to air fluctuations. Basic JDAM is just guided tail kit and can be dropped and targetted as regular bomb, which can be done relatively well anyway and guidance kit will just correcting. JDAM-ER with range up to 80km - which gives roughly 320 seconds of flight time would probably increase CEP accordingly.
Some universal military diktats. 1) A space based transmitter signal can always be overpowered by a ground based transmitter. 2) Multiple ground based transmitters can be built for the cost of a single anti-radiation missile. 3) HARMs currently are out ranged in theatre by Russian AD and AA missiles. 4) The US has less HARMs available than the number of Russian jamming/spoofing systems deployed at this time (not all are vehicular).
If harm missiles were being used by the US military it would probably be that most air defence has already been taken out. With stealth, missiles, ECM, counter ECM a jammers life span would be measured in minutes from it being interrupting signals. But this isn’t the war being fought so it’s all theories and expectations.
@@Statueshop297I think you missed his point about jammers are much less expensive than HARM missiles. You’re going to run out of HARMs before you run out of emitters.
@@xuansu9036 the crews, the vehicles and jammers, needing to train them, move them to the locations is not that cheap. There are thousands of HARM and many ways of taking out a jammer. When it is detected it can be hit with bombs, artillery etc etc.
@@Statueshop297 you do know HARM targets the antennas of such emitters, don’t you? The main equipment and crew could very well be set up at a distance to the antennas, making that very expensive missile hitting a very replaceable part. Not to mention these jammers and spoofers could very well be autonomous unmanned equipment. I What HARM is useful for is suppress radar ahead of an attack that would take out much more valuable assets, Not to deal with numerous expendable machines. Also that thousands of HARM inventory took years to build up, and would be expended in a few months at most if used as liberally as you suggested.
@@xuansu9036 what I said originally was that the air defence would be taken out first. These emitters when detected can be dealt with by a range of weapons including harm. Not exclusively harm.
_Odd that you don't mention vision recognition (topologically) derived from satellite imagery as a robust, cheap and obvious approach._ - Yeah, TERCOM with an optical sensor and AI support for terminal guidance. It'll be costly though.
Russian EW is effective because Ukraine effectively cannot contest the airspace. In a contested airspace, any jamming or spoofing emitter is liable to get HARMed.
It's the worth the other way - Ukraine depends on NATO assets like AWACS, satelites and drones that can't be shot down without escalation to direct conflict.
Infrared imaging with target recognition at final aproach makes the GPS jamming ineffective. Most Israeli air to ground weapon (eg. SPICE bombs) uses it, but GBU-53/B StormBreaker also has this feature. Terrain-contour-matching (TERCOM) is also a reliable method for weapon navigation, which existed well before the GPS-era. Tomahawk and other CM still use it.
Sometimes, being smart makes you weak. That's the problem with guided bombs. They can be deceived because they can think instead of being just a stupid bomb.
Stupid people are stubborn, smart people second guess everything. A stupid person only gets things done if they are pointed in the right direction. A smart person can get things done even if they are pointed in the wrong direction.
Sure, but it will ride on the back of existing systems, HARMs for example, and they need to be delivered from the air which makes them vulnerable, not accounting that in this particular instance you often get outranged. I'm not saying there would not be some success but for how long and, would it be enough?
It's happening right now. Unfortunately it's with very expensive sensor combinations but my Scandi former colleagues have a dedicated home on jam hardware kit ready to go. The software is what's taking time. It's simple to determine bearing of the jamming emissions, but the range is a challenge due to varying amplitude. You don't want to shoot a "dumb" home on jam over the heads of friends. In the case of the glsdb, it may end up being as simple as a timer. There are no friends past position x, so after x, then on home on jam.
@@attaque71 jammers are more expensive than home-on-jam missiles. The only reason why russian tactic is working is because it caught the west by surprise. Given time to adjust to these tactics the west will develop such systems, that is if they truly are that useful. The jamming-EW field is a russian specialty, no other western adversary seems to prioritize it so it might be too limited of a use case for the US to invest seriously in this sense. Overall it's not a great idea to rely on jamming, you're spending awful loads of money to make the enemy precision slightly worse, instead of spending those money to improve accuracy and range of your own systems.
S500 might be deployed to Crimea in near future but it is not designed for HIMARS/GMLRS - it's more like of the THAAD equivalent. Also, S300s and even S400s (withdrawn due to quality problems) were shooting GMLRS and other missiles quite well; if they failed, like on spectacular video - it was mostly due to staff mistake.
HMARS are beeing shoot down in massive scale.here and there one goes through on the other hand american ad shoot 1 in 10 down and gets blown up easily.the funny part is the US think they can with their airpower overpower Russian AD but like to forgett tha Russia has more AD than the US has aircrafts😂
I like how people say that Russia have never achieved air superiority and yet the FABs were dropping by the hundreds every day. Meanwhile JDAM and other western smart munitions rarely got used. And even got jammed when they do.
Thanks a lot for this video! Very informative! Very interesting! I think that using phased array antenna for munitions (JDAM, etc) could significantly decrease if not fully eliminate jamming and spoofing problem
@@thorluis226 As I understand it for JDAM, INS is the primary guidance, gps is used to provide corrections to that. Gbu-48 is an upgrade of paveway 2 (PAVE = LASEr designation) with GPS guidance available for when weather doesn't permit laser designation to be effective. GBU-38 is JDAM so INS + GPS and completely unrelated to gbu-48.
I DON'T KNOW if something change this last 2 months but Ukraine is using ATACMS very successful and more than that every day they are using jdams on Kharkiv region with great effect...
@@bastordd lol because a few of atacms out of a hundred fired hit a few targets and out of 500 jdams supplied to Ukraine a few hit a target. Well i guess you a right, the Russians might as well pack up and go home 🤡 try keep up bud, embarrassing yourself in a public forum isn't good for your nental health.
@@OzzyBloke that's excalibur round... We are talking about Jdam bombs... I'm not gonna waste my time with you... When people have videos to prove it... BTW 3 days to Kiev 😂😂😂😂😂😂😂
I don't understand why you so quickly dismissed anti-radiation missiles suppressing the jammers. Such missiles are already well developed, and would be the first option I would exercise.
Anti radiation missiles are another solution that should have been explored more, something that Ukraine lacks. GPS Jammer constantly emits signals and that is vulnerable to anti radiation missiles.
This video explains perfectly how I understand the issue. It even mentions the Kessler, bonus points for that! Can't wait to explore your other vids where I don't know the subject matter and learn something!! As for location accuracy, my thought is that Terminal guidance by friendly emitters with known locations could be helpful. Small devices with solar panels air dropped into trees, refining their location over time, listening for friendly queries and squaking only then.
Its ridiculous considering how easy its now to map out you family tree online just based on open source records. Huge amount of work has already been done by others, so you rarely have to do much work yourself.
Indeed if completely honest the only way to have them cheap enough for a mass consumer market at this point is to have a super low resolution of data analysis, which gives you something so vague that it's noticably less reliable than than just asking your parents or grandparents
@@alexdunphy3716 yeah, I know. and he doesn't have any idea about it. I would love to hear exactly what's rubbish and how would the dogs DNA prove anything
There are so many ways to counter GPS jamming and spoofing. But they're only available with American assets. Ukraine do not have these options, which is basically this war in a nutshell. There are various tactical and strategic problems that is specific to the Russia vs Ukraine conflict that will not be present in a Russia vs NATO war.
Yep! There are 3 new variants of Excalibur that are only in US or NATO hands. Two use a second means of navigation. Excal HTK is like Stormbreaker (SDB II) and can search for a target. Excal S is laser guided on terminal descent. The 3d (Excal 1B) can use shaped trajectories to get a favorable terminal attack angle.
Russia completely failed in their jamming efforts. Consumer-grade drones are flying with almost no issues in Ukraine, Starlink's biggest threat to its operational status is Elon Musk despite the Russian claims that Sttarlink would go down if needed. This never happened. GPS that we all have access to can be jammed with cheap devices that can be found online and truckers use them constanly to stop the tracking.
50 countries vs Russia. Including Elon musk 😂😂😂 and Russia is still winning. Imagine if India, Iran, north Korea, Chinese. Gets involved. The west will be history by now 😂😂
@@user-uk7bl3or3n apparently there are 50 countries in what we know to be Ukraine today. Unfortunately, the UN says that there is only Ukraine in Ukraine so it is 1 country. Russia attacked just 1 country, not even in top 20 military powers in the world.

@@user-uk7bl3or3n Just one country. India is an American ally and would never go to war with the US. The rest would get slaughtered on the battlefield. The only thing Ukraine gets is outdated systems. Nothing more! Yet, they still fight and Russia loses more men and equipment
It's nice to find honest and well-researched information for a change. I can't be bothered with mainstream media for anything but what not to believe. Great video as usual.
I read that DARPA has a program research which led to the development of Timing & Inertial Measurement Unit which eliminating the need of GPS but no more information after that.
My dad used to take star shots to navigate at night over Germany when he was in the RAF's 100 group (~1943-44). He said he survived because he had an excellent navigator - who used my dad's data to make the calculations as they flew.
I would like you to consider how you could use a laser emitter over the trip to confirm location by measuring expected features and when the picture disagrees with expected location it defaults to the emitter on jam
You can put the transmitters on the ground to calibrate your INS at the beginning of it's flight so it would be immune to last mile and standard frequency disruption, used to work for a company that made these use them in mining for automated trucks. Oh you can hop and encrypt as well because it doesn't have to be standard..
My information is from the 90's, and I have not kept up with advances in GPS. Back then there was the C/A (Coarse acquisition) system based on the L1 signal. Once you got roughly correct, you employ the L2 signal to get the P (precision) signal (as well as ionsphere compensation), which was encrypted. From what I recall, they do not specify if the C/A signal is still needed or not once the P signal is acquired. So based on this, I suspect if the CA signal was spoofed, that may prevent the P signal from being acquired.
How effective is GPS jamming anyways. Don't you need the jammer in between the receiver and transmitter to jam the GPS? Like can you tune the receiver to point towards space and ignore any emissions from below? Genuinely asking.
Dear Augusto I noticed what you are telling at 11:24. Now I have a new Samsung Mobil phone, before I had the Russian Yotaphone 2 and Yotaphone 3+ the Yotaphones used GPS and the GLONASS, the navigation with the phones who used both systems was fare more accurate than with the new phones who only use GPS.

Fun fact, you actually need 4 satellite signals... time is also a variable. for more accurate and cancelling signal propagation interferences, 6-7 is required for google map level navigation. if you are fast moving missile, more satellites signals are required to remove doppler effects
with 1 sat your accuracy is an infinite sphere, with 2 sats your accuracy is an infinite disc, with 3 sats your accuracy is an infinite line, with 4 sats your accuracy is a point. I'm guessing you ideally want a few more than that in case some of the signals are not getting through at any given time due with clouds, obstacles, etc..
@@voltaire229 not realy. With 4 sats your accuracy is a not infinite sphere. Additional satellites make the radius of the sphere smaller

The Russian-Ukraine war is not a good showcase of American made weapons, as such they’re not good showcases of western weapons over all which are to an extent designed with the American army in mind. IE the EU nation would be fighting a 3rd world country without the US and they won’t need the anti jamming capability. Or they’re fighting the Russians, which will mean the Americans are involved. As such American air power is heavily factored in, as well as their SEAD capabilities. These jammers would not survive long in the way they’re currently employed in that threat environment and we would more likely see sporadic jamming of focused areas of the front to cover big pushes. Don’t forget the 2 most potent air forces in the world both belong to the USA lol.
I'm a kind of guy who is more on the "cautious" side of personality. I really really love fool-proof and rugged things. Those magnetic rock formations on the earth, all sorts of gyroscopic navigation and celestial navigation really really impressed me. You can't jam a wire-guided AT missile, you can't jam the location of sun either. It seems to be that due to historical and geopolitical reasons, the Russian military tends to think a design thing in my way rather than the "cool" way. For goodness sake, the jam everything so hard that they jam themselves too, just to make sure that their enemy doesn't have the advantage either 😂
They did not forget how to determine one's location and the target's location, how to determine the direction of artillery guns in traverse and elevation, how to plan, organize and execute the operation of the elements of the fire support system with satisfactory low error level and time consumption, using analogue methods.
There are solutions for this problem. Many aircraft like a B-52 B2 will carry a star tracker accurate to 180m or so. Digital image scene correlation works so does ground mappingradar.
Russian krasnopol shell uses diferent aproach. No gps signal, itis guided by laser marking from a drone. So while they saturate area with jamming, they continue to operate with impunity
Krasnopol-M uses laser guidance, the Russians intend to use a combination of laser and Glonass with the new Krasnapol-D variant.
The L-JDAM does as well, in addition to INS and other things which cannot be mentioned.
The Airforce spent money on home-on-GPS-jammer seekers in 2014. This certainly seems like a pretty straight forward application. In the last couple of months the US Air Force is spending a modest amount of money to actually get these built. I am surprised this weapon isn’t already in the US inventory.
It was never needed because of the US previous warfare
They probably are - they probably sent the "old" stuff to Ukraine and kept the new stuff for themselves.

The United States wasted its money and that of much of the western world in Afghanistan for No real result. This a whole range of weapon systems didn’t get the upgrades they needed.

I am a radio frequency and network engineer, at least I was in my past. I worked in the field, and I have encountered many things that stop radio signals and interact with them in unexpected ways. Pine trees, for example, they may as well be made of copper. For some reason nothing can penetrate pine trees. If you don't want to get hit by a GPS guided bomb, hide in a coniferous forest lololol

Disrupting radio transmission would be an extremely effective way to stop the occupying forces from communicating or using tools against you that require RF signals. Another good rule of thumb when thinking about signals, 30 feet of elevation, that's usually how high you need to get above the ground in order to receive from cell towers on the horizon, any kind of dip in the terrain is a dead zone.
Pines? Dumbest thing i have ever read.

most northern italian will have more celtic and german traits given the amount of germanic people that settled there in the late antiquity..
Also is important to notice that by the roman reconquista of Italy (VI-VII century) the population of the entire peninsula dropped below 1ml.
That factor alone made the successive migrations of germanic people more influential on the population mix.
I am oddly happy to see a channel getting a sponsorship segment. It's like attending a child's graduation.
One solution I have considered lately is AI driven navigation. One with the ability to keep track of changes of direction and terrain recognition. The fire control technician would provide the drone with a three dimensional map to the target with accurate terrain and structure information of the possible routes. It could use the stars to help navigation but would not be necessary. Once released no amount of signal jamming or spoofing can deter it from accurate weapon delivery.
That's has been in development for about five years with more money and focus since 2022.

Excellent video. Thank you.
The reason why INS based weapon systems include GPS is because relative to the INS, GPS receiver is quite small and cheap. It augments the INS system by providing up to date position information, allowing the INS to correct/reset the accumulated drift.
For the weapon itself, outside of shielding/directional antennas, one of the best solutions to jamming is actually speed. Since INS drift is a function of time, the faster you go, the less time you spend within range of the jamming systems. When you get up to cruise missile speeds, 20-30 mile effective range of jammers, is small enough to where rather cheap and small(yet ITAR controlled) sensors can achieve a couple meter accuracy. The other solution to jamming is image recognition for terminal guidance. Using IR sensors and AI image recognition will allow target detection/tracking easily at hundreds of meters. That VASTLY decreases the required INS accuracy, while also allowing for the tracking of moving targets. INS accuracy could open up into the hundreds of meters!
For the battlespace, the solution to jamming is relatively small long endurance UAV's with directional antennas, and some radio hardware. They'd work in sets of 3 or more to triangulate the jammers. Passing the targeting data to many various ground/air weapon systems. Think of it as a counter artillery for jamming. I wouldn't be surprised if In future war, the poor soldiers who get assigned to the units who deploy jamming equipment, will having some of the shortest life expectancies on the battlefield.
I'd bet a good bit of money that whatever agency is operating the USA's ginormous SIGINT satellites, knows every single time, when a jammer is powered up.
Radio recon satellites are a thing, you just need enough of them. Then you launch a gmlr or something at the jammer

Very interesting and well made video, covering many topics in this field of warfare not often discussed. Cheers!
This has been discussed many times in the public domain. Both sides have drones that home in on jammers & radars. Ukraine also has HARM missiles specifically designed to counter these kinds of threats.
21:35 Ah my favorite subject... lateral lobes...
Ferengi? 🙂
Ballsy.
The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was.
The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
This is the best prospective answer to the jamming problem. Otis could try to integrate the quotient of the vector matrix of the positions that we're over that of the positions we are not. Then ffsletmein4321 and signiore A could claim the Fields Medal and Otis himself the Peace Nobel Prize. Hilariously exceptional comment this one above.
I think that is a Vaudvillel Skit not an engineer analysis.
I know I’m on the sofa. I just don’t know where everything else is relative the sofa
This is like a revised version of Who's On First, but for warfare pointy heads.
This guy isn't
The claim that for a JDAM a second without GPS adds a metre to the CEP is defintely wrong. A JDAM without GPS to correct it's internal INS has a CEP of 30 metres for a flight time of 100 seconds
I can easily see this being the case for longer range JDAM-ER which as wings and can be prone to air fluctuations. Basic JDAM is just guided tail kit and can be dropped and targetted as regular bomb, which can be done relatively well anyway and guidance kit will just correcting. JDAM-ER with range up to 80km - which gives roughly 320 seconds of flight time would probably increase CEP accordingly.
Your information is incredible. Thank you.

Some universal military diktats. 1) A space based transmitter signal can always be overpowered by a ground based transmitter. 2) Multiple ground based transmitters can be built for the cost of a single anti-radiation missile. 3) HARMs currently are out ranged in theatre by Russian AD and AA missiles. 4) The US has less HARMs available than the number of Russian jamming/spoofing systems deployed at this time (not all are vehicular).
If harm missiles were being used by the US military it would probably be that most air defence has already been taken out.
With stealth, missiles, ECM, counter ECM a jammers life span would be measured in minutes from it being interrupting signals.
But this isn’t the war being fought so it’s all theories and expectations.
@@Statueshop297I think you missed his point about jammers are much less expensive than HARM missiles. You’re going to run out of HARMs before you run out of emitters.
@@xuansu9036 the crews, the vehicles and jammers, needing to train them, move them to the locations is not that cheap. There are thousands of HARM and many ways of taking out a jammer. When it is detected it can be hit with bombs, artillery etc etc.

I What HARM is useful for is suppress radar ahead of an attack that would take out much more valuable assets, Not to deal with numerous expendable machines.

Infrared imaging with target recognition at final aproach makes the GPS jamming ineffective. Most Israeli air to ground weapon (eg. SPICE bombs) uses it, but GBU-53/B StormBreaker also has this feature. Terrain-contour-matching (TERCOM) is also a reliable method for weapon navigation, which existed well before the GPS-era.

Shouldn't be too complicated, to build some "home on jam" mechanism for rockets, if the jammers broadcast their position that loudly.
They are usually protected by nearby SHORAD.
Sure, but it will ride on the back of existing systems, HARMs for example, and they need to be delivered from the air which makes them vulnerable, not accounting that in this particular instance you often get outranged.
I'm not saying there would not be some success but for how long and, would it be enough?
Yes that is always a problem for active EW equipment... There are counter or at least preventive doctrines to mitigate this problem.
It's happening right now. Unfortunately it's with very expensive sensor combinations but my Scandi former colleagues have a dedicated home on jam hardware kit ready to go. The software is what's taking time.
It's simple to determine bearing of the jamming emissions, but the range is a challenge due to varying amplitude. You don't want to shoot a "dumb" home on jam over the heads of friends.
In the case of the glsdb, it may end up being as simple as a timer. There are no friends past position x, so after x, then on home on jam.
@@attaque71 jammers are more expensive than home-on-jam missiles. The only reason why russian tactic is working is because it caught the west by surprise. Given time to adjust to these tactics the west will develop such systems, that is if they truly are that useful. The jamming-EW field is a russian specialty, no other western adversary seems to prioritize it so it might be too limited of a use case for the US to invest seriously in this sense. Overall it's not a great idea to rely on jamming, you're spending awful loads of money to make the enemy precision slightly worse, instead of spending those money to improve accuracy and range of your own systems.
I mean the HMARS did just take out the S500 Russia’s newest air defense system “designed” for that threat
There is no S-500 in Ukraine. Maybe you mean S-400?
S500 might be deployed to Crimea in near future but it is not designed for HIMARS/GMLRS - it's more like of the THAAD equivalent.

There are so many ways to counter GPS jamming and spoofing. But they're only available with American assets. Ukraine do not have these options, which is basically this war in a nutshell. There are various tactical and strategic problems that is specific to the Russia vs Ukraine conflict that will not be present in a Russia vs NATO war.

My dad used to take star shots to navigate at night over Germany when he was in the RAF's 100 group (~1943-44). He said he survived because he had an excellent navigator - who used my dad's data to make the calculations as they flew.
Thanks
I would like you to consider how you could use a laser emitter over the trip to confirm location by measuring expected features and when the picture disagrees with expected location it defaults to the emitter on jam
Alright! It makes me happy when I see a sponsor. 👍👍
Jamming interval was Genius 😀
You can put the transmitters on the ground to calibrate your INS at the beginning of it's flight so it would be immune to last mile and standard frequency disruption, used to work for a company that made these use them in mining for automated trucks.
Oh you can hop and encrypt as well because it doesn't have to be standard..
My information is from the 90's, and I have not kept up with advances in GPS. Back then there was the C/A (Coarse acquisition) system based on the L1 signal. Once you got roughly correct, you employ the L2 signal to get the P (precision) signal (as well as ionsphere compensation), which was encrypted. From what I recall, they do not specify if the C/A signal is still needed or not once the P signal is acquired. So based on this, I suspect if the CA signal was spoofed, that may prevent the P signal from being acquired.
Is there any way to use the jamming signal to guide a missile in to the sender? Like HARM does to radar.
Very good! Thank you! By the way, dBm is not a dB mili volt, but is dB milk watt😊.
How effective is GPS jamming anyways. Don't you need the jammer in between the receiver and transmitter to jam the GPS? Like can you tune the receiver to point towards space and ignore any emissions from below? Genuinely asking.
Dear Augusto I noticed what you are telling at 11:24. Now I have a new Samsung Mobil phone, before I had the Russian Yotaphone 2 and Yotaphone 3+ the Yotaphones used GPS and the GLONASS, the navigation with the phones who used both systems was fare more accurate than with the new phones who only use GPS.
