A COMPUTING PROGRAM FOR TRACKING ERROR ANALYSIS OF KEPLERIAN TRAJECTORIES,

Abstract

This memorandum presents a computer program for determining the accuracy of instrumentation used in estimating the position and velocity of a vehicle in nearKeplerian motion. The accuracy with which two coordinates of the tracking stations may be estimated may also be determined. The information from a tracking network which represents an overdetermination of trajectory parameters is assumed to be combined in a general least-squares sense. The results appear as covariance matrices, confidence regions and standard deviations. The computer routine described here computes all partial derivatives from analytic formulas and provides for possible tracking-station motion limited to great-circle paths. (Author)
