Abstract

A computer model of satellite orbits was developed to illustrate difficult orbital concepts. It was also designed to analyze the positions of a satellite constellation with respect to locations on the earth as an aid to analysts. A literature review revealed that existing methods relay on drawings, expensive computers, or are satellite system specific, but that it would be possible to develop such a tool for an IMB-compatible personal computer using the Pascal language. Model capabilities selected included (1) a menu driven user interface; (2) a screen display showing satellite locations, ground track, and an earth map in one of three reference frames; and (3) three file output formats allowing satellite position information to be dumped to ASCII files for further analysis. Model validation was performed to ensure that the satellites are accurately propagated in their orbits from the NORAD two-line element sets used as an input to the model. The model should be used in instruction to bring the dynamic nature of satellite orbits to life and add a memorable perspective on the nature of various constellations. In analysis, it should be used where convenience, availability, and ease of use are vital.
