Errors in the Ephemerides of Satellites Caused by Numerical Integration.

Abstract

The theory of the Jacobi Integral is presented in the context of a coordinate frame having a varying pole and rotation rate. Plots of this quantity are shown as obtained from the numerical integration of the equations of motion of an earth satellite, and comparisons of satellite ephemerides obtained by integration at different step sizes are given. Sources of error are isolated and recommendations are made concerning use of the integration technique for ephemeris generation. (Author)
