Abstract
ENGLISH ABSTRACT: In February 1999, SUNSAT, a university developed satellite was launched for the
purposes of amateur communications. The effectiveness, performance and
integrity of SUNSAT's telemetry is evaluated in this thesis. Analytical data for
the evaluation of SUNSAT's telemetry could not be compiled since SUNSAT is
currently functional in space. SUNSAT is limited in its functions in its present
role. Hence, future roles of SUNSA T were proposed and investigated and the
effectiveness, performance and integrity in these new roles evaluated based on
the findings in technical articles on similar topics. These future roles proposed
include SUNSAT as a multi-satellite with multiple ground station configuration.
An integrity checking system was investigated and proposed to ascertain the
validity of telemetry received as well as a software package to evaluate the
performance of SUNSAT.
AFRIKAANSE OPSOMMING: In Februarie 1999 was a universiteits-ontwikkelde satelliet, SUNSAT, gelanseer met die aanvanklike doel van amateur kommunikasie. Die effektiwiteit, werkverrigting en integriteit van SUNSAT se telemetrie word in hierdie verhandeling getoets. Analitiese data van SUNSAT se telemetrie kon nie saamgestel word nie weens die feit dat SUNSAT sedert Februarie 1999 operasioneel is. Huidiglik is SUNSAT se funksies beperk en toekomstige funksies en rolle daarvan was nagevors en voorgestel. Hierdie nuwe funksies was getoets gebaseer op bevindinge in tegniese artikels op soortgelyke onderwerpe. Toekomstige funksies sluit in die gebruik van SUNSAT as In multisatelliet met die opstelling van veelvuldige grondstasies. Navorsing is ook gedoen op In integriteits-toetsing stelsel, asook 'n sagteware pakket om die werkverrigting van SUNSAT te toets. Hierdie integriteits-toetsing stelsel is voorgestel om die geldigheid te bepaal van alle telemetrie wat ontvang word.
