Ranging data is low, affecting the data to improve the accuracy

Current international satellite laser ranging stations ranging widely used frequency below 10Hz, using pulsed xenon lamp-pumped laser devices, although this ranging technology is quite mature, but the disadvantage is obvious: repetition frequency is low,  mcb circuit breaker  capture the satellite, LEO satellites for some or even undetectable data; ranging data is low, affecting the data to improve the accuracy;  electric transformer  of the laser output beam and pulse wave instability brings the system unstable and affect  electric meter  accuracy. These are restricting the Satellite Laser Ranging further scientific applications. Especially in recent years, there have been some mm-level precision scientific applications, this laser ranging system accuracy and the number of observations have raised further requirements.
