Simulation and Verification of the GOMOS Steering Front Assembly

چکیده
The GOMOS Steering Front Assembly (SFA) is essentially a two axis pointing system. It comprises of a mirror (SMU), a Mechanism Drive Electronics unit (MDE) and a Steering Front Mechanism (SFM). Unlike many other pointing systems the SFA must maintain a line of sight stability of better than 3 microrads, while subjected to considerable microvibration disturbances from the host spacecraft. This paper describes the key design drivers, the mechanism architecture, and how simulation was used to identify and solve the problems that was found during testing of the first GOMOS prototype. It also provides a brief overview of the applied modelling and simulation methods.
