摘　　要：针对我国探月工程再入返回段分离前的精度要求,在无法实现对再入返回器的三向测量情况下,提出多站接力跟踪的测量策略,以解决测定轨精度不高的问题。结合再入返回分离前的测控弧段,制定两站及三站接力跟踪的策略。利用ESA"桑巴"(SAMBA)卫星进行多站接力跟踪试验数据分析,结果表明,三站接力跟踪策略的定轨预报精度优于两站接力跟踪策略,能够实现返回器安全可靠地再入返回,可为再入返回任务分离前跟踪策略的制定提供依据。In the case of inability to achieve three-way measurements of the reentry capsule,and for meeting the return accuracy requirements of the Chinese lunar reentry capsule before separation,this paper provides a measurement strategy of relay tracking for multiple stations to solve the problem of precision.The strategies of relay tracking for two stations and three stations is developed with the arc of the re-entry test task before the separation,and the SAMBA satellite is used as an example to analyze the multiple station relay tracking data.The analysis results show that the optimal strategy of the orbit prediction precision is the three station relay tracking which is able to achieve reliable and safe reentry.This conclusion can provide a recommendation for the tracking strategy on the upcoming reentry mission before separation.
