Station-Keeping, Geostationary Orbit Maneuver, Coms

Scientific paper

In this paper, an automation algorithm of analyzing and scheduling the station-keeping maneuver is presented for Communication, Ocean and Meteorological Satellite (COMS). The perturbation analysis for keeping the position of the geostationary satellite is performed by analytic methods. The east/west and north/south station-keeping maneuvers are simulated for COMS. Weekly east/west and biweekly north/south station-keeping maneuvers are investigated for a period of one year. Various station-keeping orbital parameters are analyzed. As the position of COMS is not yet decided at either 128.2°E or 116.0°E, both cases are simulated. For the case of 128.2°E, east/west station-keeping requires Δ V of 3.50m/s and north/south station-keeping requires Δ V of 52.71m/s for the year 2009. For the case of 116.0°E, Δ V of 3.86m/s and Δ V of 52.71m/s are required for east/west and north/south station-keeping, respectively. The results show that the station-keeping maneuver of COMS is more effective at 128.2°E.
