Trajectory Analysis Program (TAP)

Abstract

The Trajectory Analysis Program (TAP) is designed specifically for use on the CDC 6000 series machine as a computational tool to generate trajectories by different mathematical formulations and to compare the results. In particular, the reference trajectory is the result of numerical integration of the equations of motion in a Cowell formulation with time as the independent variable; whereas, the comparison trajectory selected is achieved by an analytic (Pines, Kyner, or Escobal) or a numerically integrated Encke (classical or modified) formulation. A comprehensive description is presented of the algorithms implemented in TAP with emphasis on characteristics such as logic flow, equations, numerical techniques, comparison differencing, and plotting. A basic usage guide is included with complete instructions for input data preparation and explanations of output tables.
