It is not and according to this post, we were tracking wrong frequency.:
okay.
Using this TLE for Navigator:
1 98270C 26156BH 26188.34443476 -.00015589 00000-0 -30982-2 0 9990
2 98270 97.7571 88.7983 0007635 143.1901 230.9775 14.91796255 10
⦠there was a close match if I ran my computerās clock forward 5 minutes.
Of course thatās an approximation when simply going by the SNR of the downlink.
Hi from the Apolink Team!
We are currently trying out this TLE:
1 88206U 26193.97697469 +.00000352 +00000+0 +40657-4 0 00167

Still havenāt received anything, could we please get updated contacts? Thanks!
Best,
-The Apolink Team
Good afternoon,
It is possible I missed something, but can you share some details on the satellite we are searching for?
Never mind, I found the IPOS-TDSM satellite details.
Jan | PE0SAT
See next post, this analysis is invalid it wasn't after 5min but 5min before that K4KDR seen the signals
Very useful info, from a quick check, after 5 minutes there are three objects near the supposed Navigator position, 88207, 88246 and 88248. From them Iāll choose to try 88246 for now, @K4KDR please also try it and let us know if you have better results.
So, the TLE for Navigator from the analyst list, changed to use the temporary NORAD ID in DB:
Navigator
1 98270U 26193.91277489 +.00000588 +00000+0 +65431-4 0 00167

After communication with the team, we are going to track SENTINEL-1 (OSIRIS-A) with the TLE of analyst object 88262. Thus here is the latest TLE base on the space-track.org analylist list, changed to use the tempory NORAD ID in DB:
SENTINEL-1
1 98261U 26193.84045334 +.00001437 +00000+0 +14641-3 0 00149

Thanks very much. I feel bad if I didnāt explain properly, but the signal arrived 5-minutes AHEAD of where the old TLE placed it. When I applied this latest update, I noticed that the position of Navigator moved substantially farther back.
I originally spotted Navigatorās signal while tracking Marina, so an update to the TLE based on Navigatorās āearlyā arrival this morning would, as expected, move it FORWARD up in the area of Marina. Not farther to rear of those T-17 objects.
So sorry if I framed my adjustment poorly!
No problem, thanks for pointing it out, Iām checking now what objects are the best to track by fixing this confusion. ![]()
So, here is the fixed analysis for Navigator base on @K4KDR observation:
There are 4 possible objects, but one of them seems to fit better the 5min difference. The objects are 88265, 88266, 88267 and 88268. The one that fits better is 88267, so using that for tracking Navigator, here is the space-track.org analyst TLE, changed to use temporary NORAD ID:
Navigator

Thanks so much! Canāt wait to try a pass where I donāt have to adjust my tracking with computer clock changes.
The TLE changed to use the temporary NORAD ID:
IPoS-TDsM
1 98287U 26193.97697469 +.00000352 +00000+0 +40657-4 0 00167

Well thank you again for what turned out to be just some spectacular TLE work.
On tonightās 38° pass, I didnāt even know if I would SEE a downlink from Navigator. No data sidebands this time, of course, but the center residual carrier was plenty powerful enough to see - given some dish tracking that was accurate enough.
I canāt say if this was dead on or a fraction of a degree off, but either way itās working very well. Much appreciated!

TLE chosen from the last analysis from previous posts.
Unfortunately due to traveling I havenāt any updates on the fits, Iāll try later today or tomorrow. If there is any suggestions for changes let me know.
Navigator is not expected to transmit on UHF, so probably it is one of the other satellites, maybe one of the LEMUR sats.
Iām going to add it as Unknown 3 T17 in DB and use the TLE we used for Navigator and try to track it:

Here is the latest TLE that we will be using:

Hello Daniel, UHF Digipeater on MARINA received my messages, according the UHF beacon counter increased from 0 to 31 and my callsign was added to the beacon as last op. Unfortunatelly I didnāt receive the repeated message back, but other GS sent the telemetry with the repated messages. So it seems to be operational.
But I think there is some issue with the Digipeater Dashboard for UHF - it says UHF Total Digipeated Messages: 31, but UHF Last User:No data:

However in the Marina Telemetry Dashboard, there is the callsign decoded from last UHF beacon:
