This document presents the formulation, computational logic and coding information developed for the purpose of effecting the definition of geocentric satellite orbits. The rationale for this process is constructed around the recursive minimum variance data filter developed by R.E. Kalman and a specially prepared magnetic tape generated in the preprocessor AD-633 721. the trajectory portion of the program is formulated in the Encke manner and includes perturbing accelerations resulting from the first 3 harmonics of the Earths potential function, atmospheric dray, solar radiation pressure, and solar and lunar gravitation. These accelerations are integrated via an uncorrected Gauss-Jackson routine started with a fourth order Runge-Kutta process.
