The invention discloses a Beidou satellite maneuvering orbit recovery method. The method comprises the steps that S1, initial satellite state information is given; s2, based on the current satellite state information, detecting whether satellite orbital maneuver occurs in each epoch one by one; if yes, entering the step S4; if not, entering the step S3; s3, updating the state parameter values of all satellites, and returning to the step S2; and S4, processing the maneuvering orbit by adopting a combined short arc method orbit determination and packet filtering method to realize maneuvering orbit recovery. According to the method, rapid recovery of the maneuvering orbit of the Beidou satellite is realized by combining short arc method orbit determination and packet filtering, so that the navigation, positioning and time service performance of a Beidou system can be ensured under the condition that orbit maneuvering of the Beidou satellite occurs. According to the method, the orbit determination precision under the orbit maneuver condition of the satellite can be effectively improved, and the reliability of the global service capability of the Beidou No.3 system can be greatly improved.

    本发明公开了一种北斗卫星机动轨道恢复方法,包括:S1、给定初始的卫星状态信息;S2、基于当前卫星状态信息,逐个检测各历元是否发生卫星轨道机动;若是,则进入步骤S4;若否,则进入步骤S3;S3、更新所有卫星的状态参数值,并返回步骤S2;S4、采用联合短弧法定轨与分组滤波方法对机动轨道进行处理,实现机动轨道恢复。本发明联合短弧法定轨与分组滤波实现北斗卫星机动轨道的快速恢复,以期在北斗卫星发生轨道机动的情况下亦能保证北斗系统的导航、定位与授时服务性能。本方法不仅能有效提高卫星发生轨道机动情况下轨道确定的精度,还能大大提高北斗三号系统全球服务能力的可靠性。
