When PSAT is in SAFE mode, the callsign is PSAT-1 and TOCALL is APOFF.
The decode of PSAT-1 telemetry is as follows:
T#038,886,079,625,744,788,00011100
038 Means 38th (1 minute) packet.
886 means 8.86 volts (8.4V is full charge)
079 means 79 mA system current
625 is +Z temp
744 is -Z temp
788 is Battery temp
Decreasing Temperature counts mean warmer temps. Calibration for +Z/-Z are same, but for Battery is different.
T#041,875,075,619,718,785,00011100
3 minutes later +Z/-Z are still warming and at greater rate than internal battery.
For +/- Z, Count of 600 is about 30C. Count of 800 is about 0C.
For Battery, count 700 is about 30C. Count of 840 is about 0C.
Again, this second count-down to BURN is a second attempt to burn in case the first one failed. But since we hear it, then the antenna burn was successful and we need no more burn attempts.
