Baseband recording (cut with SDRAngel using FileSink)
When modulated, it looks like Orbcomm mobile telephony, but in that case the data bursts happen more often and there’s no visible carrier.
I also didn’t find anything corresponding in the Happysat’s Deadsat list.
What could it be? Zombie Orbcomm satellite or something else?
The time is in UTC (Z = Zulu = UTC) which is 11:43:04 local time. I could have made that clearer, sorry.
What did you use for the satellite tracking?
Edit: I loaded Orbcomm TLEs into Gpredict. There were Orbcomm FM18 and FM14
Yeah, I also use gpredict. I used the time controller to set the time.
Sorry, I forgot the Z was for UTC, I did try UTC too but there didn’t seem to be any close matches.
There is also a website that shows all the satellites overhead in a time range, I’ll see if I can find that again.
I just realised you already said it looks like the Orbcomm signal in the post, sorry about that! I completely missed it when I made my comment.
