从轨道方程出发，对影响卫星光链路接收机带宽的主要因素———多普勒频移进行了研究。
The Doppler frequency shift, the main factor restricting the bandwidth of receiver in inter satellite laser link, with orbit equations is calculated.
在卫星光通信的链路建立过程中，粗瞄误差不对称度较高时，同样的扫描时间限制内分行扫描可以获得更高的捕获概率。
Giving the same limit for the acquisition time, a larger acquisition probability is obtained with the raster scanning during the link foundation when the coarse pointing errors asymmetry is high.
