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:

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

ECSS-Q-60-01, SCC QPL, NASA PPL, GSFC-PPL-21 and
COL PPL have been used as a source information during
initial components selection.

ria:
For all flight components not meeting the selection criteria
a Parts Approval Document (PAD)has been initiated and
approved by ESA.
Listing all actions to be performed to accept the
components:
-Lot acceptance testing (LAT)
-material analysis
-outgassing testing
-Destructive parts analysis (DPA)
-Burn-in testing
-Total dose testing
-Single event upset testing
-…
Radia

pecific
ation:
Compatible with LEO orbit
* Total dose of 20KRad at component level
* Single event upset are limited to10-4 per day.
•Latch-up immunity is better than 100Mev-cm²/mg
The design has however taken into account more stringent
radiation environments.
