Abstract:

This report describes the SPACE-A program presently available for operational use. SPACE-A is the trajectory and observation generation portion of the Sequential Position and Covariance Estimation Program SPACE which is currently under development. The document contains a detailed analysis of the equations and models used by the program, a brief description of routines used in the program, as well as instructions for its operations. The principal applications of SPACE-A are the prediction of the space-vehicle trajectories and the generation of observational data plus other trajectory related information.
