Summary 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.
