Abstract

为了实现嫦娥四号中继星的激光测距,需要开展月球激光测距(LLR)进行技术验证。中国科学院云南天文台基于1.2m的望远镜研制了共光路LLR系统,在攻克了多项技术难题后,于2018年1月22日成功探测到Apollo 15月面反射器的回波信号,实现了LLR。多次重复实验结果表明,该LLR系统具备极弱激光信号探测能力,系统测量精度达到米级。 

Other Abstract

In order to realize the laser ranging of Chang'e-4 repeater satellite, the study of lunar laser ranging (LLR) is needed to be carried out for technical verification. Yunnan Observatories of Chinese Academy of Sciences develeps a common optical path LLR system based on the 1.2m telescope. After many technical defficulties are overcame, the echo signal from the Apollo 15 reflector on the lunar surface was successfully detected on January 22, 2018, and the LLR is realized. Repeated experimental results show that the LLR system has the ability to detect very weak laser signals, and the measurement accuracy of the system reaches meter level.
