IGSO satellite plays important part to COMPASS Navigation Satellite System and its position significantly impacts performance of the whole navigation system service. With various of perturbations and initial orbit error, ascending node longitude of IGSO satellite drift continued, which varies service area of navigation system. It's necessary to amendment longitude of the satellite ascending node to keep navigation precision periodically. Control strategies were analyzed alone, and offset of semi-major axis is determined base d on the change law of ascending node longitude. Optimum control velocity increment to amendment orbit by the means of Lagrange multiplier and a control method to maintain satellite orbit are presented. Simulation results have verified the effectiveness and convenience. This paper also provides reference of Maintenance of navigation constellation.
