摘要
天宫一号于2011年9月发射,超期服役了两年半时间之后于2016年3月处于无控状态。天宫一号是中国第一个目标飞行器和空间实验室,完成了许多空间实验任务,对我国空间站的建立有着重要的意义。天宫一号主动脱离轨道逐渐陨落,形成了一个空间碎片目标,长春站作为卫星激光测距组织的一员开展了对无控天宫一号卫星的激光测距研究。本文通过分析天宫一号卫星的特性,总结基于调整时间偏差和距离偏差的方法实现天宫一号卫星激光测距。利用长春站的卫星激光测距系统多次观测到天宫一号卫星,以2017年6月29日观测无控天宫一号卫星为例验证了本文无控天宫一号卫星激光测距方法的正确性。本文的研究成果可以为近地空间碎片、无控卫星等的激光测距提供研究基础。
Tiangong - 1 was launched in September 2011, and it was uncontrolled after two and a half years in March2016. Tiangong - 1 is the first target spacecraft and space laboratory in China, and has accomplished many space experiment tasks,which has an important significance to the establishment of our space station. Tiangong - 1 deviated from orbit voluntarily and fell gradu-ally, forming a space debris target. Changchun space observation station, as a member of the satellite laser ranging organizations, car-ried out the laser ranging research on the uncontrolled satellite Tiangong - 1. Based on the analysis of the characteristics of Tiangong -1, this thesis summarizes the achievement on the satellite laser ranging of Tiangong - 1through adjusting time deviation and range devi-ation. Tiangong - 1 satellite was observed several times using the satellite laser ranging system at Changchun space observation sta-tion. The observation of the uncontrolled satellite Tiangong - 1 on June 29, 2017 was used as an example to verify the correctness of theuncontrolled Tiangong - 1 satellite laser ranging method. The research results of this thesis can provide the research basis for laser ran-ging of terrestrial space debris, uncontrolled satellites, etc.
