| 摘 要： | 导航星座的自主定轨是提高其生存能力的重要方面，利用星间测量信息可以实现星座的自主定轨。提出了一种利用改进的Kalman滤波融合动力学信息和星间测距信息，并实时修正积分初值的自主定轨算法。采用IGS精密星历仿真星间测量值，运算结果表明该算法能获得较高的定轨精度。

| Abstract: | Autonomous orbit determination of navigation constellation based on cross-link range can improve greatly the viability of constellation.An algorithm of autonomous orbit determination is presented in this paper.This algorithm fuses dynamics data and cross-link range by improved Kalman filter,and real-time modifies integral parameters.Cross-link range is simulated based on IGS precise ephemeredes.The results show that this algorithm is feasible to precise orbit determination.At last,influence of measurement a... |
