Fault monitoring is a vital part of every satellite mission. Especially for rendezvous scenarios reliable and fast actuator fault detection is indispensable to avoid collision between both spacecraft. To reduce expensive monitoring hardware, a model-based thruster fault approach, only depending on a gyro is developed. It is able to reliably detect thruster stuck closed, thruster stuck open and leaking thruster faults in short time. Monte Carlo results produced in complete satellite simulator are presented to show fault detection and isolation performance of the proposed algorithms.
