This paper studies the effects of fog and scintillation attenuations on the performance of the vertical free‐space optical (FSO) link from the Earth to low Earth orbit (LEO) satellite. FSO link performance was investigated under different foggy conditions and turbulence by calculating the power received, achieved data rate, and link margin. Different parameters were studied such as the wavelength, the transmitted power, the divergence angle, and the diameter of receiving optical antenna. The results show that the FSO performance can be improved using 1,550‐nm wavelength, increasing the transmitted power to a range of 5 mW and reducing the divergence angle to a range of 1 μrad.

雾和闪烁对从地球到低地球轨道卫星的垂直自由空间光链路性能的影响

本文研究了雾和闪烁衰减对从地球到低地球轨道(LEO)卫星的垂直自由空间光学(FSO)链路性能的影响。通过计算接收到的功率,实现的数据速率和链路余量,研究了在不同雾条件和湍流下的FSO链路性能。研究了不同的参数,例如波长,发射功率,发散角和接收光学天线的直径。结果表明,使用1,550-nm波长可以改善FSO性能,将发射功率增加到5 mW,将发散角减小到1μrad。
