I have received LRPT a day after it launched. And like you showed. The signal fluctuated quite a bit too. And it still does. I got a decent picture tho. I might try HRPT soon. Looking forward to the directional antenna video
That's pretty cool, I used to get receive the NOAA sat passes and could get pretty good results from my DIY 120 degree dipole antenna with a SDR. I tried getting the passes from the Meteor-m sat but I never could decode a good image, always had bars or gaps, just figured it was my antenna or my cheap SDR. I've always been a bit of a geek and I just loved to tell my friends I get my weather directly from a satellite in space, no middle man. :-)
awesome job with the satellite analysis! And amazing image from the extendable QFH antenna arm. LRPT is decent and HRPT looks great. Looking forward to sample its hrpt capabilities from Greece.
Thanks for the video! Tried receiving Meteor M2-3 LRPT today, and got the same fluctuating signal issue. Only a small part of the pass got successfully decoded for me. I hope it gets fixed.
yeah - it's properly fucked. 87 deg pass, no more than 12 dB SNR, and after it went overhead the signal dropped like a stone. The antenna's pattern is definitely directional.
Anyways, the Russians say they are planning to launch «Meteor-М» № 2-4 at the end of this year. And also, they say that «Meteor-М» № 2-5 (launch in 2024) and «Meteor-М» № 2-6 (launch in 2025) are in active manufacturing.
@happysat7525 only russians parts ... 😂, we already saw, how this "sanctions" were ignored, and how western components and parts ended up in missiles, with manifacture date after 2014.
Yay, finally. I was wondering, why my signal wwass so bad, thsts might be my answer. I will try building better antena during holidays. What type of antena (Omnidirectional) would you prefer?
That would be cool to see a detailed video about cross yagi for satellites from you. I have recently made one myself from pvc pipe and tape measure, but haven’t quite tested it yet
@dereksgc I followed some articles and the tutorial from Robert Research Radios channel. I think you can make simpler and more clear one. And my antenna performs much better than a dipole, I can record the whole pass of the sat.
I would like to see you configure SDR# for Meteor m2-3. I tried 'Happy Sat' but could not follow it. I know it's a simple request but for a simple guy. TNX.
Hi Dereksgc. I follow you for some time but i never post a word. I give you my like and i have a question for you. Do you know a easy way to download any other sat images than the GOES? I found a way to download the GOES from NOAA and NASA, but i want to use another kind of satellites because i want to make comparisons. I do not have the equipment to do this, but if i can, i can download from a repository in internet. With time i want to introduce myself in the way of receiving directly, but its complex in this moments. (for money issues).
Access to NOAA data is probably the easiest. It is possible to get data from Meteosat for free from Eumetsat by using the Eumetview or Eumetsat Data Store. For other satellites, you want to search for terms such as "level 1 data" or "level 2 data", possibly "hdf" files which is the format they usually come from. Converting them into an image can be quite tricky though. Ironically in many cases it is easier to just set up the antenna yourself than to go through the complicated process of obtaining the data online as an individual
@@dereksgc Thank you for the fast reply. Well, if i need to open hdf i can use the ENVI software, but i want a chewed formad like a jpg, i also plan to make an app in kotlin-java, for view atmospheric visual info. Now i have a non released educational app for this. For academical use only. I was thinking i could find jpg files of the bands and show them separately and use it to understand details of the bands for my geoinformatic class. I am geologist and software developer, that's the reason of asking this things. Thank you for the data, i will continue searching in Eumetsat data store as you point me.
That is transmitted in the X-band at such high frequency and symbol rate that it is practically impossible to receive for the vast majority of people, including myself
Hey! Ive been struggeling with decoding Meteor-M N2-3 LRPT. Im getting a strong signal but for some reason I cant decode anything. Im assuming my recording settings are wrong, I use WFM demodulation, 2.4M sample rate and record as audio/wav (in sdr++). Do I need to record a baseband file for LRPT? Ive been told I should usually use NFM for sat decoding (atleast for APT) but sdr++ doesnt let me use the required bandwidth with NFM.
I'm having the same issue... My QFH antenna gets a perfect signal from NOAA satellites for the entire duration of the pass, but Meteor only gives a good signal for the first half of the pass and dies the moment it passes the halfway point and starts moving away from me.
Well at least now you know the issue is not on your side. Unfortunately there isn't much you can do with an omnidirectional antenna, just keep trying until you eventually get lucky and get good signal throughout the pass. Try focusing on lower elevation passes, those may be better
Mam takie wrażenie , że Meteor MN-2 dawał mocniejszy sygnał , bo na antenie QHA był dużo silniejszy sygnał na tym samym sprzęcie, niż z Meteora MN2-3 .
When I received LRPT just today, the signal was strong while the satellite was 'approaching' but dropped significantly when the satellite passed overhead.
That is probably going to be the most likely thing to happen. Sometimes you might get lucky depending whether the satellite is east or west of you and get more consistent signal
@@Smile249 How did you record it then? For digital signals you need to record the full bandwidth in its raw form, so usually best way to do it is just baseband recording the entire sampled bandwidth. This sounds like you might have recorded audio, which would result in a very small file that's almost instantly processed
what app are you using to track? cannot find it on gpredict
It is already in the standard TLE sources, you just need to update. It may not be named yet, instead of Meteor look for "2023-091A"
It's on N2YO
Forcing Gpredict to update didn't work for me for some reason. I had to save the latest weather txt and load it from that local file.
The Look4Sat Android app has it.
@@ericks1979it worked fine for me

Никогда не видел, что поворачивая тарелку вручную, без поворотного устройства будет такой классный снимок на частоте 1.7 ггц. Молодец!!!
excelent job! to je radost vidět někoho takhle talentovanýho.

Cannot be fixed, we have to live with it..

Great video on Meteor, I haven't tried this satellite yet. going to give the LRPT a go. 👍
I can confirm signals are definitely weaker just now , quite a few failures as Satdump fails to decode LRPT. Nice video thanks

In 2017 they also said that meteor-m n2-3 would launch in 2020
@@dereksgc Yep, true. We'll see what happens. But in my understanding, the «Meteor-М» № 2-4 is already fully assembled. So, we just have to hope:)
Correct № 2-4 was built under Western sanctions, so with only Russian parts.
№ 2-6 is the last in the series that supports LRPT.
@@nickpalmer_offc don't think it's assembled. On Meteor-M's wiki page, it says that 2-4 is planned, while 2-5 and 2-6 are already being assembled.

not sure if i would go for a cross yagi, might be easier to make a standard linear yagi with a few more elements
@dereksgc I followed some articles and the tutorial from Robert Research Radios channel. I think you can make simpler and more clear one.
And my antenna performs much better than a dipole, I can record the whole pass of the sat.
Awesome video as always...❤
I hope the antenna could be fixed, perhaps cycling the deployment could unstick it
Thanks for using my picture. Ever since MeteorMN3, every post I make almost immediately I got a stupid crypto scam post on my image.
IMHO you should point the C LNB as same as that helix antenna direction, facing the offset focus of dish.
I would like to see you configure SDR# for Meteor m2-3. I tried 'Happy Sat' but could not follow it. I know it's a simple request but for a simple guy. TNX.
The present actual LRPT frequency is now 137.1 MHz.
This is really cool

How about KMSS-MR (Комплекс многозональной спектральной съемки среднего разрешения) reception? Is that really hard?
That is transmitted in the X-band at such high frequency and symbol rate that it is practically impossible to receive for the vast majority of people, including myself
what did you reduce the sampling rate to?

Yep you have to use baseband. APT is the only exception where you can use audio demod, all digital signals need to be basebad/raw IQ recorded.
250ksps sample rate is enough, it will have the smallest file size when recording baseband
thank you im am still studying EM

What's the HRPT status on Meteor-M N2 and N2-2?
Meteor-M N2 is gone, Meteor-M N2-2 should now be transmitting HRPT all the time
Just tried to get a capture, I got reception and recorded it to a WAV file but can't seem to process it using SatDump. Any idea why?
You have to elaborate on what is happening. You load it into satdump, select the Meteor-M N2-X LRPT mode, and select an output folder
@@dereksgc yep did that, it attempts to process it but then just exports a blank world map once it's done.
@@Smile249 Does it show any usable dB SNR value?
@@dereksgc no, it finishes exporting in like 1 second and doesnt do anything further. Doesn't show me anything like a SNR value

Any normal sat tracking app. Make sure your TLEs are updated. It may not have its proper name yet so try looking for "2023-091A"
