| 摘 要： | 为提高深空探测器在转移轨道的自主导航能力,提出了一种基于EKF的X射线脉冲星自主导航定位系统.以X射线探测器获得的脉冲到达时间为量测量,以深空探测器轨道动力学模型为状态方程,利用扩展卡尔曼滤波算法进行状态估计.以美国火星探路者任务深空转移段为例进行了仿真实验,仿真结果表明了该方法的可行性与有效性,能够完成深空探测器转移段的自主导航任务.

| Abstract: | In order to improve the autonomous navigation ability of deep space exploration for transfer orbit,an EKF-based X-ray pulsar autonomous navigation positioning system is proposed.Using the pulse time-of-arrival obtained by X-ray detector as the measurement,and using the transfer orbit dynamic model for the deep space explorer as the state equation,we adopt the extended Kalman filter to estimate the system state.The orbit of American Mars Pathfinder is adopted to validate the navigation method.The simulation results demonstrate the feasibility and effectiveness of the proposed navigation method,it can solve autonomous navigation of deep space exploration for transfer orbit. |
