A collocation strategy has been planned and analyzed for three geostationary satellites in the same longitude control box. The orbit determination error analysis is performed when only one ground station is used for the angle tracking and ranging. Based on the orbit determination errors, the station-keeping bands are allocated for seven-day East/West and 14-day North/South station-keeping maneuver cycles. The eccentricity control circle and inclination control box for individual satellites are allocated for the collocation. The eccentricity vector and inclination vector separation method is applied for the collocation, and the rnaneuver schedule is planned to rninimize the operational load by avoiding simultaneous maneuvers. A total of fourteen wecks of station-keeping maneuvers are performed for three KOREASAT satellites, collocated in 116deg E+/-0.05deg longitude band.
