Hi all,


I have one day off and tried to command COMPASS in full sunlight.

The first pass (for Europe) this morning was low, only 6°. All commands were
accepted and confirmed several time by COMPASS.

At 0801UTC the beacon came with 00 compass ff0660000000002100009800ff

It shows, that the heater was still on – in spite of confirmed commands.  I
will try the next pass (nearly 90°)

73, Mike
