A COMPUTING PROGRAM FOR DETERMINING CERTAIN STATISTICAL PARAMETERS ASSOCIATED WITH POSITION AND VELOCITY ERRORS FOR ORBITING AND RE-ENTERING SPACE VEHICLES

Abstract

For most applications of satellites and re-entering space vehicles, one must be concerned with the accuracy with which position and velocity can be determined and predicted while on orbit and at the time of earth impact. A computing program is described for estimating, in terms of confidence regions, the on-orbit and impact errors of such vehicles. In estimating impact errors, guidance errors are combined with orbital prediction errors. The analytically determined sensitivity coefficients are used in this program as a means of error propagation. Their expression as functions of orbital parameters may make them useful for other purposes, such as estimating performance requirements of tracking and prediction systems.
