Goal: Built a satellite bus for future missions
which only needs minor adjustments
Main Design Objective:
„No matter what, MOVE shall create and deliver
data!”
Highest Design Goal:
“Robustness rather than Efficiency”
-> Famous last words

After 2 weeks deployment and successful
communications:
No data beacons
Only CW beacon every 60 sec
Propably software damage
Possible scenario:
−Hard power reset
−Errors during write operation
−Booting not possible anymore
