摘要

经过1997年8月对中科院长春人造卫星观测站卫星激光测距系统的技术改造

使系统的观测精度和稳定性都有了很大的提高.主要是采用了量子效率高、能自动补偿、时间游动小、快响应的单光子光电雪崩二极管和一套便携式激光测距校准系统

以及建立三个近地标准靶等.结果使测距内符精度由原来的6cm左右

提高到现在的小于2cm（单次）和1cm左右（标准点数据）

系统的长期稳定性由原来的4cm左右

提高到现在小于2cm

系统测距的距离偏差小于6cm

时间偏差小于50μs.

Abstract

After the technical restructure implemented in August 1997 in Changchun Artificial Satellite Observatory

the range precision and stability of the satellite laser ranging system have been greatly improved.A high quantum efficiency

low time walk

compensated

low work voltage and fast response time single photon avalanche diode was applied to the system

besides the establishment of a portable calibration system and three new near ground targets.Now

the system produces subcentimeter single shot precision and precision in mm level for normal point data.The long term system stability is improved from 4 cm to better than 2 cm

the range bias is less than 6 cm

and the time bias is less than 50 μs.
