Abstract
The TOPEX/POSEIDON spacecraft was launched on August 10, 1992. This paper presents data on the measured performance of the ASTRA Star Trackers supplied by Hughes Danbury Optical Systems (HDOS) for this satellite. The HDOS ASTRA Star Tracker is a charge coupled device (CCD), microprocessor based replacement for the NASA Standard Fixed Head Star Tracker. The position and magnitude accuracy of the star trackers computed from measured flight data are compared with ground measurements and system models. The performance of novel transient rejection algorithms implemented in the ASTRA Star Tracker which allows uninterrupted operation in the South Atlantic Anomaly (SAA) where the sensor is subjected to high proton flux levels, also are presented.
