Dear Sir,
Attached are telemetry on FM voice for your study. During telemetry announcement, FM signal sttoped, maybe due to battery voltage down.
August 14, 2011 at 1049 UTC, Telemetry on FM voice, just after AOS MET is ?? minutes (I could not copy with QSB/Noise) IHU Temp is plus ?? degrees C (I could not copy with QSB/Noise) Control Panel Temp is plus 61 degrees C Battery Voltage is 36.014 Battery Current is minus 4 milliAmps
August 14, 2011 at 1051 UTC, Telemetry on FM voice MET is 69 minutes IHU Temp is plus 48 degrees C Control Panel Temp is plus 61 degrees C Battery Voltage is 36.014 Battery Current is minus 8 milliAmps
August 14, 2011 at 1053 UTC, Telemetry on FM voice MET is 72 minutes IHU Temp is plus 48 degrees C Control Panel Temp is plus 6? degrees C Battery Voltage is 31.
FM carrier stopped just at this point, after announcement of battery voltage drop down to 31 V. It is not LOS yet. Not calculated, but orbit prediction of this pass is VVN. Satellite goes into eclipse during this pass. I think ARISSAT1 lost solar panel power and stopped soon.
I wish this data helps you. Thank you, Fujio JO1XWH
