- A bare overview of all the currently operating geostationary weather satellites, and pointing out the ones you can receive images from yourself.
Also sorry to all the Indian viewers who spot the map mistake, I simply didn't fill the borders fully.

Re: Himawari and JCSAT-2B, a bit of searching shows it uses a DVB-S2 receiver on C band using something called "KenCast Fazzt" software, so it's sending IP packets.
Also thanks for covering options from the whole globe, not just Europe & hi from Australia!
*_"If you are at like more or less Z degrees inclination which means directly above the equator your orbital period will more or less match the rotational period of the earth meaning that with respect to the ground the satellite is is basically standing in the same spot 24/7"_*
Arthur C. Clarke got that *_RIGHT In 1945!!!_*
Back in the mid 1970's my neighbor and I built a system to receive *_SMS GOES 2!_*
US East coast here, thanks for all the details! Look forward to receiving GOES 16 & 18.
I always find these videos just as I'm about to start receiving the sats theyre talking about! Exactly the info I was looking for, thanks as always!
I started working on the 1.7 ghz hrpt, and your videos helped me a lot. thanks from Greece.
i'm from India and i too am keen in downlinking INSAT signals. how did you modify the LNB for 4.7GHz, most LNBs i find seem to go only upto 4.2GHz.
great video as always !!
Thank you for a very informative video. I am an old man but new to this hobby and your videos have been quite informative. Thank you very much for sharing.
I have a 1m dish antenna (no offset) that I found in a dumpster in Czechia and I want to try to receive Elektro L3 with it, but it has very short amount of space between the boom (idk that thing that holds the feed) and the antenna itself. I think I'll try to make an extension from some sort of mesh (to make it 1.2-1.4m diameter), but I don't think I can fit a helical feed inside. Do you think the double cross would work fine with that? Or is there something else I can do?
liked before watching :-)
Nice overview about whats possible. Thank you and stay dry ( a lot of rain here to for the past 6 weeks) 😀
Great Video
Always very informative
Please keep them Coming

Just what I needed.... Thank you brother... Video much appreciated...🙏
As usual another good video. Let me acquire a 6 feet dish then i will try insats.
Great video!
This really helped me make sense of all the different guides out there on all the different satellites and transmissions. Thanks for all the detail.
Great video! Do you think Elektro L2 transmits LRIT or HRIT? Im in the UK so don't think I will get L3 here as looks like I am right on the edge of coverage. Cheers!
No, unfortunately there seem to be issues with this satellite that among other things prevent it from transmitting LRIT and HRIT in the 1.7 GHz band. Images can be received in the X-band at 7500 MHz but the setup for that is a lot more complicated and would require a very large dish antenna in the UK
@@dereksgc Thanks for the reply! Much appreciated! So there are no GEO weather sats I can decode from the UK do you think? BTW, you have such great content and you appear to have extensive knowledge of this topic, thanks for sharing your knowledge. Matt
@@TechMindsOfficial i know some people in the UK who have managed to receive GOES-16 HRIT, but that is the very edge of its coverage
Very good video, seems to cover it all. I think you missed out CMAcast - China’s equivalent of Himawaricast. But that’s encrypted anyway.
Elektro L3/4 seems to be the best option really, if it wasn’t for the over exposed images.
As for GOES 15, I assume it will stop short of GOES 13. Otherwise they have to move GOES 13 out of the way if GOES 15 takes its position.
13 and 15 could share the same spot (or near enough to not interfere with each other), but it is also possible 13 will just be retired because its imager has degraded
ok so how does european meteosat get there information down to earth,because that is what i am missing in your story. And i know there is a eumeteocast service on 10 East i believe, you can get some hardware and a software license key and decode that information.
They use dishes in excess of 10m diameter. Meteosat-11 and earlier use 1.7 GHz but at very little power, Met-12 will use 26 GHz. Eumetcast is a solution but requires a costly receiver and much more involved hardware setup
Thank you for this video; I'm just starting with SDR stuff and receiving NOAA APT. I'm from India and have a C band LNB and a 6-foot dish. I am interested in INSAT 3D. If you could share more information(How I can connect C band LNB with RTL SDR dongle), that would be very helpful.
I have a video on connecting ku-band LNBs to an SDR, C-band is the same thing, just doesn't use the multiple LO. Also have videos on the bias tees I used to power them. Not sure if RTL-SDR is enough for insat imager, but it should work for the infrared sounder downlinks if you actually can get it strong enough.
I am doing the same stuff and I am also from india.
I think we should join forces😂
@@aakashprasad114 i think the same lmao
gk-2a lrit is honestly kinda boring. its only a single channel IR full disk and some supplementary downlinked forecasts/wind data of the korean region.
sadly its pretty much all i can pick up from my location in australia
You can try GK-2A HRIT.
@@eswnl1 no I can not, I have horrible line of sight
@@LunaWuna What about the Fengyun satellites? Or the Elektro-L satellites? And GK-2A LRIT might only be a single IR channel, but because it's transmitted every 10 minutes it allows for some nice animations. It is also very strong, doable without a dish in some cases.
I have a 1m dish antenna (no offset) that I found in a dumpster in Czechia and I want to try to receive Elektro L3 with it, but it has very short amount of space between the boom (idk that thing that holds the feed) and the antenna itself. I think I'll try to make an extension from some sort of mesh (to make it 1.2-1.4m diameter), but I don't think I can fit a helical feed inside. Do you think the bi-quad would work fine with that? Or is there something else I can do?
You can try a biquad but that will have small loss due to wrong polarization. You can try to use helix with narrow spacing and only 3-4 turns, that will be even better suited for prime focus dish
@@dereksgc do you think that that low number of turns will be sufficient? 3 years ago I was using 7 turns on my offset antenna for HRPT, but got little to no signal... I blamed it on the low quality LNA and moved on to other projects,now I'm slowly getting back to satellite reception
