摘　　要：电推力器在静止轨道卫星上应用越来越广泛,特别是基于电推力器进行南北位置保持,可以有效节省推进剂.提出改进的GPS星历参数解析算法,在此基础上考虑包含电推力模型在内多摄动项模型进行地面精密轨道计算,采用微分修正法,提出一种地球同步轨道注入参数方法,该方法可应用于星上自主完成基于电推力器的南北位置保持.仿真算例表明使用该方法得到的轨道注入参数,卫星能够在保证姿态确定精度的同时,完成南北位置保持任务.The application of electric propulsion system in geostationary satellite is widely developed re-cently. 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 percise orbit determination including electric propulsion model,a geostationary orbitinjection parameters approach of differential correction is proposed,which can be used in south-north station keeping based on electric propulsion system aytonmously.The effectiveness of south-north station keeping and the precision of attitude determanation are validated with the approach proposed by simulation.
