IAFSIM, a real time closed loop simulator of the Italsat Attitude and Orbit Control Subsystem (AOCS), is described. Conventional applications are discussed and the main results of several IAFSIM simulation runs, which cover the main AOCS modes of operation during the various Italsat mission phases, are presented. The simulation results are compared with the actual AOCS test results highlighting the possibility of tuning the IAFSIM to reproduce with high fidelity the real AOCS performances. IAFSIM possible future applications are described, including implementation and testing of nonconventional control philosophies for attitude control in case of primary failures. The development of algorithms using the IAFSIM as a fundamental tool of research is demonstrated.
