Thesis (MScEng)--Stellenbosch University, 2002. / ENGLISH ABSTRACT: There is a large variety of telemetry recervmg software currently available for the
reception of telemetry information from different satellites. Most of the software used in
receiving telemetry data is satellite specific. Hence, a user-friendly way is needed to
make telemetry data easily accessible. A satellite-based web server is aimed at providing
telemetry information to any standard web browser as a way of bringing space
technology awareness to the people. Two different satellite-based web server methods are
examined in this thesis. Based on the evaluation, the on-board File server with proxy
server was proposed for satellite-based web server development. This requires that the
File server be ported to the on-board computer of the satellite. The web proxy server is
placed on the ground segment with the necessary communication requirements to
communicate with the on-board File server. In the absence of satellite, the satellite-based
web server was successfully implemented on two computers, laying a good foundation
for implementation on the on-board computer of the satellite (OBe). / AFRIKAANSE OPSOMMING: Daar is 'n groot verskeidenheid telemetrie ontvangs sagteware huidiglik beskikbaar vir
die ontvangs van telemetrie informasie vanaf verskillende satelliete. Die meeste van die
sagteware wat gebruik word om telemetrie data te ontvang is satelliet spesifiek.
Gevolglik, 'n gebruikers vriendelike metode is nodig om telemetrie data maklik
beskikbaar te maak. 'n Satelliet-gebaseerde web-bediener word beoog om telemetrie
informasie te verskaf aan enige standaard web-blaaier as 'n metode om mense bewus te
maak van ruimte tegnologie. Twee verskillende satelliet gebaseerde web-bediener
metodes salondersoek word in hierdie tesis. Gebaseer op 'n evaluering, word die
aanboord leêr-bediener met instaanbediener voorgestel vir satelliet-gebaseerde webbediener
ontwikkeling. Hiervoor is dit nodig dat die leêr-bediener na die aanboord
rekenaar van die satelliet gepoort word. Die web instaanbediener word op die grond
segment geplaas met die nodige kommunikasie benodighede, om te kommunikeer met
die aanboord leêr-bediener. In die afwesigheid van die satelliet was die satellietgebaseerde
web-bediener met sukses geïmplementeer op twee rekenaars, met die gevolg
dat 'n goeie fondasie gelê is vir die implementering op die aanboord rekenaar van die
satelliet (OBC).
