In a contract for the European Space Agency, Verhaert Space

developed a state-off-the-art control unit for small but high

demanding satellites.

Built on the experience gained with the PROBA-I satellite that has

been in daily use since its launch in 2001. This next generation

avionics has been developed and will have its first in-orbit

demonstration in 2008 as the satellite control unit for PROBA-II.

The goal of this contract was to improve even further the PROBA-I satellite-

bus (currently in orbit) in terms of:

·Scala

And to make this satellite control unit not only suitable for the PROBA-II, but

for any other small satellite.

A detailed look at the above top-level requirements identifies however some

contradictions:

·Low power consumption versus high computing performance

·Low mass and volume versus modularity

·Highly integrated system versus testability

This presentation describes how the ADPMS design has provided ananswer

to all above criteria without penalising one of them.

The benefits:

�the protocol can be changed to future versions

without hardware redesign

�Authentication can be added in software

�Additional VC-ID’s can be easily added

�Additional M

AP-ID’s can be easily added

�the (hardware) failure rate decreases since less logic

is needed

�nolarge FPGAneeded anymore

�noPROM needed anymore

�noradiation-hard static RAM

needed anymore

�the power consumption is reduced

�virtually no extra power required since

the

processor perform

ance needed is less than 10 KIPS

•Latch-up immunity is better than 100Mev-cm²/mg

The design has however taken into account more stringent

radiation environments.
