A technique for maintaining a satellite in an assigned orbit without control or intervention from the ground. Autonomously obtained navigational data provide a measurement of the actual orbit in which the satellite is traveling. So long as the measured orbit conforms to a desired orbit to within a preselected tolerance, periodic corrections of equal magnitude are made to the satellite\s velocity, based on a prediction of the effect of atmospheric drag on the orbit. Measurement of the orbit is made by observation of the time that the satellite passes a re...


A control system for autonomously maintaining an earth-orbiting satellite in a desired orbit, the system comprising: means located on the satellite for sensing successive positions of the satellite in its orbit and determining from the successive positions the actual orbit of the satellite; orbit correction computation means, also located on the satellite, for periodically computing an orbital velocity correction by comparing the determined actual orbit of the satellite to a desired orbit; means for converting the computed orbital velocity correction int...
