The ongoing and future spacecrafts of ESA are often based on the sophisticated three axis attitude and orbit control subsystem using different technologies. A major problem occurring during the system development is to ensure that the whole subsystem has the expected dynamic behavior, once integrated in the spacecraft. The aim of a test policy is to provide an answer to this problem. An efficient test method should ensure the AOCS operates in a realistic dynamic and kinematic way. A good choice is a compromise between purely static test using all equipment assembled onboard, the satellite motion being simulated on an external computer, and a complete three axis simulation table, which is a sophisticated solution. The configuration using a one axis air bearing table combinated with an IR stimuli controlled in a transverse direction was selected for OTS and MAROTS development, together with a test sequence in two steps.
