Abstract

Many satellites need to know their attitude. A star tracking system is able to provide this information accurately. The objective of this thesis project is to develop a precise, robust and fast algorithm chain for a star tracker that performs better than the currently used algorithms on that star tracker. The performance of this algorithm chain was verified by simulation. A lost-in-space solution can be done in 200 ms, with a precision of 0.6 arc seconds in pitch and yaw and a precision of 4.8 arc seconds in roll. This performance exceeds that of the old algorithm chain.
