Pointing Mechanisms

Scientific paper

EADS Astrium has developed an Antenna Pointing Mechanism (APM) for Geo-stationary orbits which operates successfully in space since December 2003. Typically launch loads are partly or completely off-loaded from the APM with Hold Down and Release Mechanism HDRM. For small antennas in the range of up to 2 kg it was the objective to completely eliminate the HDRM with the help of a Pre-loaded Mechanical End-stop (PME) that would together with the APM actuators serve as a secondary load path. The PME is loaded and released with the actuator torque.
