Paper Abstract

The HD-1002 (also known as MACS) solid state star trackers being built by Hughes Danbury Optical Systems, Inc. (HDOS) for Martin Marietta Astro Space Division for use in their Modular Attitude Control Systems (MACS) Module are improved and modified versions of the ASTRA1 star trackers now in use on board the TOPEX/POSEIDON satellite. The ASTRA1 design was based on the pioneering work accomplished at HDOS over the past decade. Along with the set of trackers being built by HDOS for Space Station Freedom, these trackers answer a variety of application requirements for spacecraft attitude control systems. This paper addresses the main features of the MACS trackers, their role in the MACS Module, and summarizes the excellent preliminary performance results of the tracker, as supported by measured test data.
