Greencube Dashboard not listing contributed frames

SatNOGS Software
1

Hi,

Over the last few weeks, I’ve been able to see my Greencube telemetry contributions uploading to the Greencube dashboard. Four days ago, these stopped showing up.

I am currently operating two RX stations. N6RFM in FN41iq and N6RFM/5 in EM12jw. I had seen listings previously but these have now disappeared.

If I look at Satnogs database reception results, my contributions are showing up.

Any help appreciated.

Tks es 73,

Bob
N6RFM

I’ve just had a look and it seems those frames you were submitting are not (yet) supported by the decoder! If I pick a random one from DB and try to decode it locally, I am getting an empty result, see:

❯ echo "82923900765A00D063707C1B831C093200000000000000000000000000000000000000000F14140007D02E00071307D0012C19320050220A00000520002900000000000900070004000000037D55E60E" | xxd -r -p - > ../sampledata/greencube/n6rfm_01.bin
❯ decode_frame Greencube ../sampledata/greencube/n6rfm_01.bin
{}

Pinging @k8dp on that…

Thanks Patrick. Scott K4KDR found a solution. The CRC at the end of the frame seemed to cause the problem. Removal of the CRC resolves the problem.

see - SatNogs upload w/CRC does NOT appear on Grafana Dashboard · Issue #415 · daniestevez/gr-satellites · GitHub for additional information.

Best,
Bob

TLM Id 0x765A isn’t (yet) supported by the GreenCube telemetry decoder–this is on my todo list! 0x1D03 (Digipeater frame) also coming soon…

The issue Bob encountered is due to extra bytes (CRC) being passed to the DB by gr-satellites. I ran into this issue as well, but didn’t realize the reason until Scott brought it to our attention.
