英文摘要：

The satellite laser ranging is one of the important application technologies for the ground-basedoptical-electronic telescope system, and the distance of the space debris is directly measured to improve the orbitaccuracy. Based on the laser ranging telescope with the aperture of 60cm at the Shanghai Astronomical Observatory, thespace debris laser ranging system is set up with the development of a high power laser system of hundreds hertzrepetition rate and a laser signal detection system of high efficiency. The routine laser observation of space debris maybe realized with the measured distance from 500 km to 2600 km, the cross section from 0.3 m2 to 20 m2, the rangingprecision of better than 1 m, for accurately measuring the space debris. In addition, the method of monitoring the spacetargets in the daytime is also studied preliminarily, and the stars brighter than six magnitude of brightness are observedto make the regional pointing error correction model. The method can be applied in the monitoring and guiding for thedaylight space debris laser ranging.
