Keyword测量与计量 一发两收 激光测距 空间碎片

一发两收激光测距技术可提高卫星激光测距系统的探测能力,因此,一发两收测距模式在空间碎片激光测距中得到了很好的应用。实测获得的合距离可用于解算目标位置等参数,然而解算过程中存在精密定轨法方程复杂的困难,而将合距离归算到目标到各站点的距离能够简化法方程。结合中国科学院云南天文台1.2 m望远镜10 Hz共光路激光测距接收系统和53 cm双筒望远镜千赫兹常规卫星激光测距系统,建立了一个一发两收高精度激光测距试验平台,并对过境的多圈卫星开展了激光测距试验,直接测量获得了目标的合距离以及目标至各站点的距离。试验结果表明:卫星到1.2m望远镜的距离与到53 cm双筒望远镜的距离之差符合预期,距离测量精度达到厘米量级,获得的卫星测量数据可用于异地收发空间碎片激光测距系统的距离归算方法研究。 

Other 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.
