我国新一代大型流动卫星激光测距仪由中国地震局地震研究所研制成功，于2012年流动到湖北咸宁进行首次流动观测（见图）。

该仪器望远镜口径达到1米，具有白天观测和千赫兹测距能力，流动方式采样半挂车运载，仪器整体长10米，宽2.5米，高3.9米，重15吨，观测时天文圆顶可以自动开启。据项目负责人郭唐永研究员介绍，该仪器设计能力可以观测到3万6千公里的地球同步卫星，其测距精度可达毫米级。该测距仪为国家重大科学工程中国大陆构造环境监测网络支持的项目，之后将承担陆态网络的常规流动监测任务。

该卫星激光测距仪是在原来的小型仪器TROS－I（口径38厘米）的基础上发展起来的，TROS－I曾于2000在新疆承担过神舟4号激光精密定轨观测任务以及为总装备部某基地的雷达标校进行的激光观测任务；2008年4月13日在北京房山站首次成功实现了我国的KHz激光测距功能；08－09年流动到韩国开展为期一年的合作观测（视频）。现在新型TROS1000在自动化、白天观测和KHz测距等方面有较大的性能提升，特别是TROS1000的接收口径达到1米，是目前世界上最大的流动卫星激光观测系统，这为将来TROS1000进行非合作目标观测和激光测月实验打下了基础。

Large-scale mobile satellite laser ranging system firstly carried out observation task in Xianning city,Hubeiprovince in 2012. The instrument moves by the mobile method of semitrailer-shipment, with telescope diameter of 1 meter, 10 meters length, 2.5 meters width, 3.9meters height and 15 tons weight. It has the capability of daytime observation and kHz ranging, and can automatically open the astronomical dome during the observation. According to the report from Guo Tangyong Researcher Fellow who has been always responsible for the project, this system can observe the geosynchronous satellite, 36 thousand kilometers away from the earth, and ranging accuracy can reach millimeter.

This new Satellite Laser Ranging system is designed based on the previous smaller system TROS-Ⅰwith 38cm telescope aperture, which has finished successfully the Shenzhou-Ⅳ laser precision orbit determination observation mission in Xinjiang in 2000 years. And this SLR system achieved firstly the function of KHz ranging in Fangshan,Beijingcity in April 13th 2008, and carried out successfully a one-year cooperative observation inKoreafrom 2008 to 2009. Nowadays this new generation SLR system TROS-1000 has improved performance in many aspects, such as automation, daytime observation and KHz ranging and so on. Especially its receiving aperture reaches 1 meter, which makes it become the largest mobile Satellite Laser Ranging system in the world.
