1.2 m Telescope Satellite Co-Optical Path kHz Laser Ranging System
Kilo-Hertz (kHz) laser ranging is one of effective methods to increase the measurement frequency and improve the accuracy of normal point (NP). Principle and method of realizing common optical path kHz laser ranging are analyzed, which include optical path, circuit and computer control etc. Novel concept of rotation shutter is proposed to build kHz system, and control system of 1.2 m telescope common optical path kHz laser ranging has been developed. It has been successfully used for routine observation. Actual observations show that the system performs well and runs stable. The ground target ranging accuracy is about 5 mm, and satellite ranging accuracy is better than 2.0 cm.
