WHAT GOING ON WITH AO-92 . I HEAR IT IS IN SAFE MODE.IS THER A PROBLEM WITH AO-92 ??????BOB/KB5SQG
AO-92 is currently dropping into safe mode due to low voltage near the end of eclipse on some orbits. Right now that's the end of the ascending, evening passes, and it's also dependent on the load the previous orbit. As soon as the satellite hits illumination again, it automatically comes out of safe mode. It's unfortunate that this is happening over North America right now, but it's the control software preventing the batteries from over discharge, which is a good thing.

Yes, just had it drop into safe-mode towards the end of our nightly pass, roughly 2 hours after it entered eclipse. --Hans

Hello Hans and the list--
AO-92 is currently experiencing around 35 mins of ellipse and then 60 minutes of sunlight per orbit. I read the "..roughly 2 hours after it entered eclipse" and that caught my attention and as they say, "made me look." ;-)

Probably me being tired late at night: I guess I meant 20 minutes. My bad. --Hans
