Approximate Planetary Ephemerides for SLBM (Submarine Launched Ballistic Missile) Applications

Abstract

This report describes a procedure for estimating planetary orbital parameters which are used to generate approximate planetary positions based on a simple ephemeris model. The computer program developed to implement this procedure are also documented, and an analysis of the residual errors arising from the approximation model is provided. The method described is based on the classical method of Least Squares Differential Corrections which applies to stable nonlinear estimation problems. The actual estimation process was carried out in terms of equinoctal elements to avoid any possible numerical problems and the observations employed were obtained from the precise ephemeris model, DE-92, developed by NASA's Jet Propulsion Laboratory. Originator-supplied keywords: Least squares, Planet, Extract, Lestsq, Geoeq, Delalp, Select, Plot, Delapm.
