VEGA Cubesat status report


20:00 UTC

ALMASat-1  received and decoded until ~ 1300 UTC - see note below
e-St@r     not received
Goliath    not received
MaSat-1    received and decoded
PW-Sat     received and decoded
Robusta    not received
UniCubeSat not received
Xatcobeo   received and decoded

Since my 1350 UTC pass I can’t decode the signal of ALMASat-1 anymore. There is a kind of flutter, a very short intermitted signal – so no success with decoding of the beacons in all further passes.


behavior of VEGA cubesats illumination


At the moment we are in an eclipse-free periode (ending on Feb 20). In the mid of March we will see a bad illumination of all cubesats.
