[amsat-bb] HuskySat telemetry

This doesn’t explain why some data was getting uploaded from the same 4 or so ground stations. Can you please elaborate on  why only these  stations were able to post data and no one else?

I have investigated the issue with processing HuskySat telemetry and implemented a fix.  For this spacecraft we have some more stringent time keeping considerations, hence the request for data to be "real time".  The check to make sure that data was real time was failing because the spacecraft clock has drifted further than expected.  The drift in the clock should not have been an issue but I had a logic error.  The error is fixed and I am re-processing missed telemetry.  That may take a while, but already I have loaded about 9000 frames.

 

Feel free to email me if you see any issues.

I just want to acknowledge that I have seen the messages here and will investigate as soon as I can.  No telemetry is lost.  If the frames were rejected in error then they are still on the server and I will process them if I can.

We probably have to wait for Chris to check.  Is it that your packets are
not showing up on the leaderboard?

Thanks for collecting telemetry anyway.  We need to figure this out.
