Station-Keeping Maneuver Simulation for the Koreasat Spacecraft Using Mission Analysis Software

Abstract

A series of east/west and north/south station-keeping maneuvers were simulated for the KOREASAT spacecraft which has to be maintained within ±0°.05 at the nominal longitude of 116°E. Weekly and biweekly based station-keeping maneuver plannings were used, and weekend maneuvers were avoided. All of the station-keeping maneuver plannings and executions were performed using KOREASAT Mission Analysis Software on VAX/VMS operating system. Fourteen weeks station-keeping maneuvers were performed and various station-keeping orbital parameters were obtained.
