The invention provides a lunar satellite formation autonomous navigation method based on inter-satellite ranging information. The lunar satellite formation autonomous navigation method comprises three parts of orbit dynamics model establishment, collaborative observation model establishment and navigation filtering algorithm data fusion. The invention provides an autonomous navigation method based on inter-satellite distance measurement and angle measurement information, which establishes a high-precision dynamic model containing 165-order moon non-spherical perturbation for moon satellite formation. The system can operate independently of a ground station, and high-precision autonomous navigation of the lunar satellite formation is realized only by using on-orbit observation data.
本发明提供一种基于星间测距信息的月球卫星编队自主导航方法,包含轨道动力学模型建立、协同观测模型建立和导航滤波算法数据融合三个部分。本发明为月球卫星编队建立了包含165阶次月球非球形摄动的高精度动力学模型,提出了一种基于星间测距和测角信息的自主导航方法。能够独立于地面站运行,仅利用在轨观测数据实现月球卫星编队的高精度自主导航。
