Abstract:

An outline is given on the development of a differential correction theory for lunar and space probes. To overcome the singularities inherent in differential processes with conventional two-body descriptions of the path, as the eccentricity passes through unity in either the parabolic or rectilinear sense, a unified formulation of the two-body equations was developed. The differential correction procedure over is based upon an ephemeris, integrated in Encke form by special perturbations, and upon differential expressions derived from the unified two-body equations. The report includes experimentation with simulated range, range-rate, azimuth, altitude, right ascension andor declination data to evaluate the performance of the resulting IBM 709 program.
