CORRECTION OF PERIGEE ARGUMENT WITH LONGITUDE CONTROL FOR GEOSYNCHRONOUS SATELLITES IN INCLINED ECCENTRIC ORBIT

摘要

P Method for controlling the orbit of a satellite by maintaining the location of its perigee while simultaneously preventing a reference point on the orbit from moving too far from a normal position on earth. This changes the semi-major axis of the orbit, which, when disturbed away from the geosynchronous value, creates a drift speed relative to the earth. To correct the perigee argument and maintain the prescribed tolerance for the position of the track on the ground, multiple maneuvers must be performed to control the speed of drift. The relation between the maximum admissible speed variation and the time between maneuvers is defined by the required correction of the perigee argument and the admissible displacement of the reference point. /P
