摘要
激光测距是空间飞行器轨道测定精度最高的一种技术。传统激光测距是测量激光信号的往返传输时间实现空间飞行器距离和轨道的测定。对于超月球距离的空间飞行器,该测量方式已不适用,必须采用单向激光传输,激光能量随距离平方衰减,其作用范围可超过月球达到行星际空间,这将是行星际激光测距的重要测量方式。利用地面激光测距系统,对一颗载有光子探测器和时间计时器的同步轨道卫星成功进行了单向激光测距实验,并与该卫星激光往返传输所测量的卫星距离进行了比较和分析,验证了单向激光测距的可行性。该测量实验为进一步研究单向激光测距技术及我国行星际空间飞行器激光测量终端系统设计提供了一定的参考。
Abstract
Laser ranging is a kind of high precise measuring technology for spacecraft orbit determination. The traditional laser ranging is to measure the roundtrip flight time of laser pulse to collect precise measurement of range that allows the spacecraft to achieve its requirement for precise orbit determination. For the long distance spacecrafts farther than the moon, the above measuring way is not suitable and the one-way range measurement via laser pulse time-of-flight from ground stations to spacecrafts should be utilized. For this measuring mode, the laser signal energy falls off only as square of distance and the laser signal can reach the place beyond the moon to the planets. The one way laser measurement will become a significant way for interplanetary laser ranging. By using the ground satellite laser ranging system, laser measuring experiments to geosynchronous satellite equipping laser detector and timing counter are successfully implemented. The comparison and analysis for laser data obtained from both the one way and the roundtrip flight measurements are carried out. The measuring results validate the feasibility of one way laser ranging. The measuring experiments provides reference for further study on the one-way laser ranging and design of laser measuring terminal system for interplanetary spacecraft in future.
