[amsat-bb] Re: COMPASS commands

[Mike Rupprecht]

Hi Doug, all

this beacon looks good. COMPASS made no hard reset and all settings are valid.

Yesterday evening I heard the beacon and the temperature was 0° . So I commanded the satellite to switch off the heater at 0 degr. It seems that has worked. After this command I sent the treshold value to -50 degr. 

Now we can see that the heater is still off (also at low temperatures). This evening I will try to change the voltage treshold - maybe I can switch COMPASS into powersafe mode. That means we can hear the beacon every 3 minutes.

Please stay tuned and listen to the beacon. Thank's a lot for all your efforts.

73, MIke
