| 摘 要： | 卫星质心改正值(简称CoM,Center-of-Mass)是卫星激光测距系统中的一个重要参量,准确估算该参量有助于提高卫星激光测距精度.本文以Lageos卫星为例,应用概率理论以及卫星上的角反射器对光子的反射概率与反射器的光学截面成正比,建立了球形激光卫星的CoM数学模型,并计算了几颗球形卫星的CoM值,还对一般的情况进行了讨论.

| Abstract: | Center of Mass (CoM) is a significant parameter of satellite laser ranging system.Estimating the parameter exactly is helpful to improving the measuring precision of satellite laser ranging.In the article,taking the satellite Lageos for example,based on the theory of probability and the reflecting probability of photons for retro reflectors on satellites is proportional to the cross sections of the retro reflectors,the mathematical model of Center of Mass (CoM) for spherical satellites is built up.The corrections of CoMs of several spherical satellites are calculated and the general situations are also considered. |
