ESPOD FUNCTIONAL DESCRIPTION

Abstract

ESPOD is a general orbit determination program prepared for use by the SPACETRACK/SPADATS Center, Ent Air Force Base, Colorado Springs, Colorado. Its primary purpose is to determine satellite orbits. It determines the elements of a satellite orbit and a covariance matrix of uncertainty in the determination, starting from some initial estimate of these elements and correcting it in accordance with observational data. It predicts the future position and velocity of the satellite from the best elements obtained. The program includes a unique collection of mathematical, statistical, and operational techniques to make it operate rapidly and automatically and to produce high precision in the results.
