A Geostationary OrbitInjection Parameters Approach in NorthSouth Station Keeping Based on Electric Propulsion System

The application of electric propulsion system in geostationary satellite is widely developed recently. Especially, propellant is saved when electric propulsion system is used in southnorth station keeping. The modified analytical algorithm including GPS ephemeris parameters is presented. Then considering the precise orbit determination including electric propulsion model, a geostationary orbitinjection parameters approach of differential correction is proposed, which can be used in southnorth station keeping based on electric propulsion system autonomously. The effectiveness of southnorth station keeping and the precision of attitude determination are validated with the approach proposed by simulation.
