28 October 1996 Analysis of the NEAR star tracker flight data
Author Affiliations +
The NEAR spacecraft uses a star tracker for precision attitude determination and employs techniques for autonomous star identification and tracking. Outdoor test data and flight data have been analyzed to characterize the performance. Both types of data show good agreement in general with calibration data. Results from the outdoor tests were used to improve models of the tracker in simulations used for software development and test. This paper briefly describes the guidance and control system and star tracker, simulations, and star catalogs. The remainder of the paper discusses the analysis of the flight data and compares the performance results with calibration data.
