Scientific paper

It is shown that complicated and voluminous ephemeris computations can be carried out in a microprocessor such that satellite positions and velocities can be computed at a high rate (10 Hz). It is noted that the accuracies obtained in this way are a function of the model and are not dependent on the capability of the microprocessor. The model used is one which uses general perturbation methods. It includes the perturbative effects of the sun, moon, and the geopotential harmonic J2.
