[amsat-bb] COMPASS-1 needs your help

[Mike Rupprecht]

Hi all,

 

We got an single beacon last night. COMPASS-1 did an complete restart and the tresholds for heater and battery voltages should be new set.

 

Without changing the tresholds the heater will be on if the temperature inside goes under 10 deg. 

The batteries are weak and this leads to an crash.
