Fix baudrate for SWSU satellites #421

Closed sv1 closed 1 year ago

daniestevez commented 1 year ago

Thank you. This is related to #397. What is the source that motivates the change to 1145 baud? Does it come from some official documentation from the project?

sv1 commented 1 year ago

Hello Daniel,

unfortunately I can not find any official documentation but this is what I have used and successfully decoded telemetry with direwolf and gr_satellites.

Does it fail to decode with the baudrate we currently have in the repository?

sv1 commented 1 year ago

Yes! that is why I started looking into this and made that change!

daniestevez commented 1 year ago

Can you share the recordings you used? It's interesting because earlier when we attempted to measure the baudrates of these satellites it turned out that the baudrates were around 1130-1135, which is well away from 1145. It could be that their baudrates are not so stable and keep changing.

I do not have recordings, only real-time decoding!

daniestevez commented 1 year ago

Then maybe it's useful to record the next time you try to receive.

Closing, since this has long been inactive and I'm not keen on changing the baudrates without some kind of precise measurement.
