By running ikhnos, for now I’ve changed the NORAD IDs we follow in the following way, note that it is still early for identification and for some of the satellites more than one TLE sets fits for now but we chose only one to follow:
Hello, Geoscan here. We have been able to get our telemetry with AX.25 format packet from our satellite transmitter an hour ago. So our cubesat is operational. I hope you’ll be able to receive signal from it! It looks like that our satellite should have 53375 NORAD rather than 53383, but it’s tbd still.
Here is our protocol. We are open to any questions and eager to communicate with satnogs community. GRTP.pdf (339.9 KB)
We have contacted IARU beforehand as soon as we got a place on this launch, a callsign from our national administration and figured out what we have to do. We really wanted this mission to be as open as possible. We want to follow all conventions and communicate with radio amateurs around the world. To be able to follow our educational mission. But sadly IARU don’t want to see us as such, somehow. But we try to do anything we can. This is our first ever mission:)
What software should we use to decode frames from your satellite? Standard UZ7HO HS-SoundModem FSK 9K6 modem? What mode? USB or W-FM? I was able to receive signals from your satellite but I couldn´t decode them with my usual Windows tools.
@fredy Certainly may be the case, I’ve got a STRF observation from SatNOGS Network - Observation 6314779 that shows a couple signals in the last several seconds that are lining up with 53378 @ 437.550.
With the space-track.org TLE assigned we are a step closer to identifications. Here are the results after analyzing with ikhnos the latest observations:

I have not seen the names “Polytech Universe 1 & 2” mentioned here, but following up on a tweet:
… I recorded a low pass of Objects 53371/53372 and after replay & analysis, find that their downlinks are 62.5k LoRa.
The LoRa parameters shown in the following tweet are probably not all exactly correct, but they were close enough for me to get a decode from one of the dirty packets from this low pass. So, I’ll be interested to see confirmation eventually of what these 2 objects are and hopefully even some info about the telemetry payload
