论文摘要
月球激光射程（LLR）实验已积累了50年的数据，这些数据可以提高从地面站到月球表面上的激光逆转录器阵列（LRAS）的准确性。即将到来的十年提供了几个机会，通过部署下一代单角农月逆转录器和主动激光发音器，从而在数据精度上打破了新的基础。这可能会扩大LLR站网络。月球动力学模型和分析工具具有改善和充分利用毫米级LLR数据允许的长时间基线和精度。概述了一些模型限制以供将来的努力。差异观察技术将有助于减轻一些主要的限制因素，并达到前所未有的准确性。这样的观察和技术可能可以检测几个了解地球系统和深农内部动力学所需的微妙特征。 LLR模型的改进将影响包括月球和行星科学，地球科学，基本物理学，天体力学和ephemerides在内的多学科领域。
The Lunar Laser Ranging (LLR) experiment has accumulated 50 years of range data of improving accuracy from ground stations to the laser retroreflector arrays (LRAs) on the lunar surface. The upcoming decade offers several opportunities to break new ground in data precision through the deployment of the next generation of single corner-cube lunar retroreflectors and active laser transponders. This is likely to expand the LLR station network. Lunar dynamical models and analysis tools have the potential to improve and fully exploit the long temporal baseline and precision allowed by millimetric LLR data. Some of the model limitations are outlined for future efforts. Differential observation techniques will help mitigate some of the primary limiting factors and reach unprecedented accuracy. Such observations and techniques may enable the detection of several subtle signatures required to understand the dynamics of the Earth-Moon system and the deep lunar interior. LLR model improvements would impact multi-disciplinary fields that include lunar and planetary science, Earth science, fundamental physics, celestial mechanics and ephemerides.
