Telemetry reports showed that the temperature aboard ARISSat-1/KEDR had been rising as atmospheric drag began to affect the satellite. Final temperatures received via ARISSatTLM reported this data:
IHU 75 ° C / 167.0 ° F PSU 76 ° C / 168.8 ° F RF 88 ° C / 190.4 ° F Control Panel 61 ° C / 141.8 ° F Experiment 64 ° C / 147.2 ° F
Tracking data from Space Command gave a Predicted Decay Time 0700 GMT +/- 3 Hours on January 4. Telemetry report narrows the impact time window to about 4 hours. The predicted decay location is 12.7° S, 354.3° E, an open part of the South Atlantic, well west of Angola. Send reports to the amsat-bb If you heard the satellite, even briefly, after 0600 UTC. This will help confirm the actual impact point.
Stations receiving telemetry from ARISSat-1 at any time over the last few months, please forward all of your .CSV telemetry files to telemetry AT arissattlm.org.
