BEESAT-2  (NoradID 39136) is expected to re-enter into Earth’s atmosphere in the evening of next Wednesday, 2024-01-31, or during Thursday, 2024-02-01. As with BEESAT-4  last September we will try to activate worldwide transmission of standard telemetry (APID 41,1,2,4, see our Information for Radio Amateurs  and Telemetry Format ) every 10 seconds, beginning about two days prior (we will notify). If SatNOGS stations are not running gr-satellites with MobiTUB-2 decoder it would be nice to record IQ data. We then could decode telemetry locally and submit decoded telemetry afterwards. Also running STRF scans at 435.95 MHz during passes over our Berlin, Germany, ground station (and later worldwide) could help to determinate TLEs as from BEESAT-4 and -3 we know that they will be change fast once we are getting closer to re-erntry.
To all helping HAMs: Many thanks in advance for your support!

Added to leosatdata.com and enabled by default.
thank you very much for uploading the received frames. Were you able to observe also another pass?
I didn’t know leosatdata before, but thanks for activating BEESAT-2 by default When I understand it, from my brief look, correctly to get actual frames a GMSK decoder in the jradio project would be necessary? Despite that also the waterfall plots can be useful to detect until when the satellite is alive. And I saw there are already some succesfull observations
Yes, jradio decoder is embedded into r2cloud that can send data to leosatdata.com, that can send data further to SatNOGS.
Data I uploaded to SatNOGS and TU-Berlin DB
Last pass today over Minsk
MaxEl 17°, huge QRM
Thank you EU1SAT for all your recordings and uploads We have received your data well At a later time when all this is behind us I can give you csv files with the decoded telemetry from your station if you are interested in that. But we also plan to add a ksy file to SatNOGS so they should be also decoded there.
Our sources are saying that BEESAT-2 will burn up at about 09:51 UTC at 2024-02-01. Today in the evening we encountered the first problems with doppler shift drift and sadly neither our own nor other STRF ground station (that we know of) functioned correctly or was active. We will have to see how good the reception is tomorrow. First Berlin pass will be at around 10:50 UTC.
Last pass over Minsk
2024-02-01 10:06-10:40 UTC Nothing Heard over Minsk
I think BEESAT-2 has decayed. As mentioned above 09:51 UTC was the prediction given to us on Tuesday and we also did not receive anything during the 10:17 and 11:45 passes over Berlin. I will write later today a little bit more.
