Abstract

高重频卫星激光测距系统中,激光脉冲飞行时间通过事件计时器分别测量主波和回波时刻获得。为了采用更高重频且高精度的事件计时器,将Guidetech公司的GT668SLR-1事件计时器应用于中国科学院云南天文台的12m望远镜激光测距系统,对其结构原理进行分析,并利用其测量由信号发生器产生的固定信号、地靶测距和卫星测距等试验,采集数据的处理结果达到激光测距精度要求,由此判定GT668SLR-1事件计时器可用做卫星激光测距系统的时间测量单元。 

Other Abstract

In high-frequency satellite laser ranging ( SLR) system, the flight time of laser pulse is acquired by an event timer (ET) which measures the event epochs of laser transmitting and photon receiving. In order to put an ET with higher frequency and precision into good use, the GT668SLR-1 type from Guidetech is introduced into the 1.2m telescope SLR system during our system upgrading, its principle and structure are analyzed. By means of measuring fixed signals from signal generator, ground target measurement and satellite laser ranging, the new event timer is tested for the SLR system, and the processing results of sampled data meet the demand of ranging standards. Therefore, it is concluded that the GT668SLR-1 type is capable to be integrated as the time measuring unit for the SLR system.
