Re: AO-40 Beacon



Yes it helps.

this spin modulation that everybody that copies telemetry has noticed,  is
only temporary? My guess is that because they need to orient the Satellite,
they are spinning it to maintain the attitude, whereas, once it  is in its
final orbit it will be three axis, reaction wheels stabilized and it won't
spin anymore?
Does anybody know if this is true?
