The Tracking Instrument’s Accuracy Evaluation with GPS

Shouxin Zhang, Xurong Dong, and Haizhong Xie

Abstract:	Various tracking devices such as radar and optical instruments are widely used in space technology, for instance, target tracking, orbit determination and so on. One of the most important things for using those tracking devices is the calibration which is essential for maintaining the high tracking accuracy. This paper presents the methodology and test results of using GPS for the performance test of the tracking instrument, with emphasis on its tracking accuracy evaluation and systematic error estimation. Several flight tests have been conducted in 1997, which all gave the results with the accuracy in the order of some centimeters. It has been shown that GPS offers longer tracking arc, easy implementation and minimized cost etc., compared to the traditional calibration methods.
