The quasi-stationary satellite orbit

Three or four satellites equally spaced in a quasi-stationary satellite orbit can provide continuous earth coverage, but with advantages and disadvantages with respect to satellites in geostationary satellite orbit. This report presents general purpose equations, computer programs, and tables for studying orbits with any reference longitude and inclination. Results of a sample system having eleven earth stations and a specific orbit with a reference longitude of 75 degrees west and an inclination of 60 degrees are also presented.
