To be a Sun-synchronous orbit (SSO), the orbit must have a certain value of nodal precession rate, which equals 360°/year. However, the value of nodal precession rate is usually drifted by orbit perturbations, mainly by the oblateness of the Earth and atmospheric drag, to be no longer 360°/year as expected for SSO. Thus, the local time of the satellite will change too, so it needs to be corrected by some correction maneuvers. In this research, the authors studied station-keeping planning for SSO satellite via inclination correction maneuver by simulation using GMAT, a software developed by NASA, with a finite-burn propulsion approach. In this research, LAPAN-A4 satellite is chosen to be the satellite that will be simulated. Some alternative plans of inclination correction maneuver based on maneuvering intervals are chosen, they are maneuvers for every 2 months, 4 months, 6 months, 12 months, and 24 months. The simulation results show that the station keeping planning with correction maneuver for every 2 months is recommended. This alternative gives the lowest fuel consumption so that the fuel and launch cost will be minimum, and the local time drift that is still may be tolerated.
