分析了作为参考轨道的严格回归轨道与卫星在轨运行状态的相对运动关系,提出近地遥感卫星的管道导航方法.由于参考轨道的设计只考虑高精度的地球非球形摄动,与在轨卫星的动力学环境存在差别,这导致两者之间存在切航向漂移.基于高精度的轨道动力学模型和位置确定方法,设计了卫星与参考轨道采样点的切航向对齐算法,从而获取了卫星相对参考轨道采样点的相位时间偏差和卫星在参考轨道编队坐标系切航向平面内的相对运动轨迹,进而引入椭圆的“最小二乘适配法”获取相对运动轨迹的特征量.所研究的管道导航方法可应用于基于GNSS测量数据的卫星自主轨迹保持. The relationship between the orbit of the orbit and the orbit of the satellite is analyzed, and the method of navigation for the near-Earth remote sensing satellite is proposed.As the design of the reference orbit only considers the non-spherical perturbation with high precision, Which leads to the drift of the sag direction between the two.According to the high-accuracy orbit dynamics model and the position determination method, the alignment algorithm of the cutting point of the satellite and the reference track is designed, and the satellite relative The relative movement trajectory of the satellites in the cutting plane of the reference orbit formation coordinate system and the elliptic least square fitting method are used to obtain the relative motion trajectory characteristics of the studied pipeline navigation The method can be applied to satellite autonomous trajectory conservation based on GNSS measurements.
