This paper discusses the fault protection tesing of the Attitude and Articulation Control Subsystem (AACS) of the Galileo spacecraft. The need for an autonomous fault protection system on an interplanetary spacecraft is discussed. Galileo requirements for the detection and response of specific hardware failures is discussed along with the fault protection software design and implementation. The test beds and test methods used for fault protection testing are described. The paper concludes with a presentation of the results of this testing with an emphasis on requirement and design changes that were made as a result of these tests.
