| 摘 要： | 利用三轴磁强计的测量信息可实时地确定卫星轨道。采用扩展卡尔曼滤波作为处理磁测自主定轨问题的滤波算法．并以地磁场强度幅值作为测量值，建立了近地卫星磁测自主定轨的数学模型。在数学模型的基础上实现了基于PC机、dSPACE一体化系统的原型化(Prototyping)实验。该原型化实验对磁测自主定轨的方案、理论、算法及实时运行特性做了进一步的验证。

| Abstract: | Autonomous orbit determination of LEO satellite can be achieved based on the measurement data of the onboard three axis magnetometer. Extended Kalman filter (EKF) is used for a filter algorithm of autonomous orbit determination. Using the magnitude of earth's magnetic field vector as the measurement variable, the numerical model of autonomous orbit determination is established in this paper. The model is run in the integrative system that was made up of PC and dSPACE. The project, the theory, the algorithm and the real-time characteristic on autonomous orbit determination was validated by the prototyping system. |
