HUCSat telemetry upload – NORAD ID 98291 vs 69794

Generic

Hello SatNOGS community,

I am currently receiving HUCSat (WP2XZJ) telemetry with my experimental LoRa ground station and I have a question regarding the correct NORAD ID to use when submitting telemetry to the SatNOGS DB through the SiDS telemetry API.

The HUCSat entry in SatNOGS DB currently shows:

  • Temporary NORAD ID: 98291

  • Followed NORAD ID: 69794

  • Callsign: WP2XZJ

  • Frequency: 437.400 MHz

My ground station is successfully receiving HUCSat frames. For example, a recent reception was:

Satellite: HUCSAT
NORAD used by my station: 69794
Frequency: 437.400 MHz
Frame length: 16 bytes
RSSI: -110.7 dBm
SNR: -12.8 dB
ASCII payload includes: WP2XZJ

My station reports successful telemetry submissions to SatNOGS, but it does not appear in the “Most Recent Observers” section for HUCSat.

I noticed that the SatNOGS HUCSat page is still identified by 98291, while the satellite is now followed using the confirmed NORAD ID 69794.

Could you please clarify which ID should currently be used in the noradID field when submitting HUCSat telemetry through the SiDS/API?

Should an external telemetry uploader submit:

noradID=69794

or, while the SatNOGS DB entry still uses the temporary ID:

noradID=98291

I would also like to know whether SatNOGS automatically associates telemetry submitted using the followed NORAD ID (69794) with the existing HUCSat DB entry (98291), or whether the telemetry submission still needs to use the temporary ID.

Best regards,

Gustavo, LW2DTZ

This happens because we haven’t merged yet the entry with the (temporary) NORAD ID 98291 with the entry with NORAD ID 69794.

SiDS is based on the NORAD ID, so the frames you sent are saved under the satellite entry with NORAD ID 69794. After merging the two entries, unfortunately this needs to be done manually, at least for now, all the data will be associated with the merged entry.

I suggest you continue to send the data to 69794.

Out of curiosity, what if someone submits to both IDs (temporary and followed) - will there exist two identical entries of each packet after merging?

Yes, there will be two frames with the same data/metadata.
