A few days ago students from TU Berlin finally managed to recover the 2009 launched and since 2013 ceased functioning BEESAT-1 (SatNOGS) back to life.
That is just right for its 15th anniversary in space, which is today on 23th.
To celebrate that, BEESAT-1 will today send telemetry over Europe on 435.950 MHz in 4k8 MOBITEX according the following schedule.
Times in UTC:
07:26 - 07:40
09:04 - 09:17
20:56 - 21:09
22:33 - 22:47
QSL cards could be possible.
edit << I was wrong, TechnoSat Modem won’t decode BEESAT-1 MOBITEX frames, sorry. >>
You are right, it’s also Mobitex protocol and 4k8 is sufficient, but while UZ7HO’s Modem listens for a D-Star bit and frame sync of CCCC 5765 the attached sync marker on BEESAT-1 is 1ACFFC1D. This is already one point at which a D-Star modem will discard a BEESAT-1 frame.
UZ7HO’s High-Speed SoundModem is built to decode BEESAT-2 and -4.
Both satellites using Mobitex-NX, whereas BEESAT-1 uses the standard Mobitex format.
EA4GPZ pointed the difference between both formats out:
The only difference between the standard Mobitex protocol and the Mobitex-NX protocol is that a callsign is included after the frame header and before the data blocks.
This is why you can read Callsign: right before the blocks start.
And because BEESAT-1 doesn’t send a callsign, all the blocks cannot be decoded.
Would you mind asking UZ7HO to modify his SoundModem to decode BEESAT-1 frames as well?
