Hello,
Regarding Observation 4965181 … it appears to show a strong signal, any idea as to why there is not any decoded data?
Thanks, Abraham-XE3ADC

Native SatNOGS has no decoder for CubeSX-HSE.

Have a look at satnogs_gr-satellites, there is also a post on this community for more details and experiences.

And yes the signal is strong enough to be decoded, here some output:

Thanks for the info!!, I’ll follow up on satnogs_gr-satellites…I gather you use gr-satellites with the observation’s ogg file to obtain the decode, right?
best regards de XE3ADC, Abraham

You can use the ogg file direct with GNURadio 3.9 and gr_satellites but if you use GNURadio 3.8 and gr_satellites you first need to convert the ogg file to a wav.

This can be done with ffmpeg -i <input file.ogg> <output_file.wav> then you can execute:

gr_satellites <norad id> --wavfile <audio file.ogg> --samp_rate 48e3 or
gr_satellites <norad id> --wavfile <audio file.wav> --samp_rate 48e3

gr_satellites --list_satellites will show you al list with all supported satellites.
