The evaluation of an ARM-based on-board computer for a low earth orbit satellite

Thesis (MScEng)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: The use of commercial-off-the-shelf (COTS) components and emerging technologies in
satellite systems has become increasingly popular over the past few years. This is mainly due
to advances in radiation shielding and system-level reliability improving techniques. The use
of a new generation commercial processor in the design of a satellite's on-board computer
(OBC) is now considered a feasible option.
The aim of this thesis was to evaluate the use of a commercial grade ARM processor in a low
earth orbit (LEO) microsatellite on-board computer. The process began with the selection of
the most suitable ARM processor for an aBC design. A typical aBC system was developed
for the chosen processor, in order to test its functionality and performance in anOBC design. / AFRIKAANSE OPSOMMING: Die afgelope paar jaar het die gebruik van gewone kommersiële komponente en die nuutste
tegnologie in satelliet stelsels heelwat toegeneem. Dit kan grootliks toeskryf word aan die
vordering in bestralings afskerming en stelselvlak betroubaarheid tegnieke. Die gebruik van
'n nuwe generasie kommersiële verwerker in die ontwerp van 'n satellite aanboord rekenaar
(AR) is nou prakties uitvoerbaar.
Die doel van hierdie tesis was om die gebruik van 'n ARM verwerker in 'n lae
aardwentelbaan mikrosatelliet aanboord rekenaar te evalueer. Eerstens moes die mees
geskikte kommersiële ARM verwerker vir 'n AR ontwerp gevind word. Daarna is 'n tipiese
AR stelselontwikkel om die verwerker se funksionaliteit en werkverrigting te toets.
