The testing of spacecraft Attitude and Orbit Control Subsystems (AOCS) from the early design up to in-flight is described. Three generic AOCS test classes, model philosophy, standardization, subsystem static test methods, subsystem dynamic test methods, generic test equipment, and test facilities are covered. It is suggested that test scheduling should aim to find problems and errors as early as possible. System level tests should be delayed in favor of detailed testing of the AOCS (unit level) and in particular subsystem level testing. Onboard AOCS software poses testing problems, especially when RAM located. There is a shift from airbearing-type dynamic tests to servotable-type dynamic tests, mainly due to increasing spacecraft size, structural flexibility, and multibody dynamics concepts.
