摘要
目前,国际上卫星自主轨道确定已受到了极大的关注,卫星定轨向高精度、高自主性方向发展。自主定轨方法多种多样,获取定轨信息的方法与自主定轨测量设备紧密联系在一起。就组合大视场星敏感器卫星自主定轨方法,建立了太阳引力摄动下的广义卡尔曼滤波模型,且进行了计算机仿真;通过对不同初始轨道高度情况的计算机仿真,给出了太阳引力对卫星轨道的影响;通过对东方红三号(DFH-3)卫星进行仿真和结果对比,说明了该自主定轨方法、所建滤波模型和算法的有效性。
At present, autonomous orbit determination for satellite has attracted more attention in the world, its development tends to high precision and self- determination. There are various methods in this aspect,and the method of receiving information to determine orbit is closely related to measure apparatus. In this paper,the extended Kalman filtering model is given under the solar perturbation for this orbit determination method by large field of view star sensors,and the computer simulation is done. The results show the orbital perturbation at different initial orbit altitudes under the action of solar gravitation. The DFH - 3 satellite is simulated and the result is compared with existing data about DFH - 3 satellite,the effectiveness of this orbit determination method and the corresponding model and algorithm are shown.
