Experiment on kHz laser ranging at Wuhan satellite laser ranging station

The kHz satellite laser ranging (SLR) system can effectively obtain a large quantity of observation data by laser emission at high repetition rate. Based on the kHz experiment at the Wuhan SLR station, the paper introduces the ranging method and the operation principle of kHz laser, and analyzes the influencing factors of echo detection in high repetition frequency. The experimental results show that the data quantity is increased by 1 to 2 orders of magnitude, and the single measurement precision is improved for the medium earth orbit and low earth orbit satellite tracking observations．
