中文摘要：

简要介绍了用于中国科学院国家天文台与阿根廷San Juan大学合作观测与研究的一个高精度卫星激光测距（SLR）系统。该望远镜口径为60cm的SLR系统由中国研制，于2005年秋被运往阿根廷，安装在阿根廷国立San Juan大学天文台，San Juan大学建立了观测室，准备了工作条件。该系统于2006年2月底完成调试并开始运行。在过去的两年间，该系统保持了良好的工作状态，由于San Juan具有良好的天气条件，该系统取得了丰富的高精度观测资料。国际激光测距服务认为该仪器的工作对国际激光测距系统是重要的，希望对其增加白天测距的功能。文章也简单介绍了该SLR站未来升级改造和发展的计划。

英文摘要：

This paper briefly describes a Satellite Laser Ranging （SLR） system with high precision, which is built for the cooperative observation and research of the National Astronomical Observatories of the Chinese Academy of Sciences and the San Juan University of Argentina. The CH-AR SLR system, with the telescope diameter 60 cm, is made by the Chinese side. In the autumn of 2005, it was moved to Argentina and then installed in the observatory of San Juan University. The San Juan University built the observational room and prepared the working conditions for the SLR system. The debugging of the system has been completed and it started to work in the end of February, 2006. Due to the good working status of the system maintained by both sides and the good weather conditions at San Juan, the system has yielded excellent observational data in the past two years. The International Laser Ranging Service regards the SLR system as an important contribution and hopes that the daylight tracking will be added to the SLR system. The development plan of the SLR system in the future is briefly discussed here as well.
