摘　　要：实现导航星座的自主定轨对提高星座自主性具有主要意义。分析了基于星间测距的导航星座定轨方法存在的缺点，提出了利用改进Kalman滤波融合星间测距测向信息的自主定轨方法。利用GPS（global position system）星座的IGS（International GPS services）精密轨道模拟星间测距测向数据，仿真结果表明该方法能够有效提高定轨的精度和稳定性。Autonomous orbit determination of navigation constellation plays an important role in increasing autonomy of constellation. Shortcoming of orbit determination method of navigation constellation based on crosslink range is analyzed. A new method of autonomous orbit determination is put forward in this paper. Improved Kalman filter is utilized to fuse erosslink range data and orientation observation in this method. Data of crosslink range and orientation observation is simulated utilizing IGS precise orbit of GPS constellation. The results show that this method can improve the accuracy and stability of orbit determination.
