Abstract:
The bi-static laser ranging technology can improve the detection capability of the laser ranging system. Therefore, the bi-static laser ranging mode has been well applied to the space debris laser ranging. The measured total distance can be used to estimate parameters such as the target positions. However, it encounters difficulties from the complexity of the normal equations involved in the precise orbit determination, and reducing the total distance to the distance from the target to each station (reduced distance) can simplify the normal equations. In this paper, a high-precision laser ranging test platform with one transmission and two receptions was established by combining the Yunnan Observatory's 1.2 m telescope 10 Hz common optical path laser ranging system with the 53 cm binoculars kilohertz conventional laser ranging system. Multiple passing satellites were conducted in the laser ranging experiment, and the directly measured total distance and the distance from the target to stations were obtained. The results show that differences between the distance from the target to the 1.2 m telescope and to the 53 cm binoculars are in line with expectation, and the distance precision reaches the order of centimeters, which could be used to study the distance reduction method for the debris laser ranging system of off-site transceiver.
