A digital-computer program for predicting the motion of satellites over long periods of time and in the presence of major perturbations. The program, called the Area Inspection Program (AIP), is designed to compute accurately and inexpensively the position of a satellite relative to several ground stations at once. It is written in FORTRAN IV for the IBM 7044 computer and consists of only one program, with no utility routines except those usually found on a system-library tape, such as SQRT, SIN, and COS. The AIP prints revolution number, area number, local time at the satellite, distance between the satellite and the ground station, the coordinates of the satellite when it enters and leaves a range circle around a ground station, and the corresponding times. These quantities can be computed and printed sequentially for several different ground stations as the satellite moves along its orbit. 60 pp.
