Utveckling och implementering av elektronik för en stjärnkamera (Swedish)
Abstract [en]

Star trackers are essential instruments commonly used on satellites. They provide

precise measurement of the orientation of a satellite and are part of the attitude

control system. For cubesats star trackers need to be small, consume low

power and preferably cheap to manufacture. In this thesis work the electronics for

a miniature star tracker has been developed. A star detection algorithm has been

implemented in hardware logic, tested and verified. A platform for continued work

is presented and future improvements of the current implementation are discussed.

Abstract [sv]

Stjärnkameror är vanligt förekommande instrument på satelliter. De tillhandahåller

information om satellitens orientering med mycket hög precision och är

en viktig del i satellitens reglersystem. För kubsatelliter måste dessa vara små,

strömsnåla och helst billiga att tillverka. I detta examensarbete har elektroniken

för en sådan stjärnkamera utvecklats. En algoritm som detekterar stjärnor har implementerats

i hårdvara, testats och verifierats. En hårdvaruplattform som fortsatt

arbete kan utgå ifrån har skapats och förslag på förbättringar diskuteras.
