Paper Abstract

Laser beam scintillation of a ground station to a satellite path are presented. After the up-link laser beam propagated to the satellite, the laser beam intensity distribution was varied by atmospheric turbulence. The variance of the up- link logarithmic-amplitude intensity fluctuation was about 0.5 and the maximum duration for the satellite receiver to be able to receive an optical power more than the communication detector sensitivity was about 50 mili-seconds in weak atmospheric turbulence condition. The maximum down- link time duration was about 0.3 seconds. The main cause of the down-link fluctuation can be considered as a fine pointing mirror angle variation in case of an up-link received power fading.
