Abstract

Fluctuation in the intensity of a downlink (satellite-to-ground) laser beam is examined by first measuring the acquisition time and pointing error of a satellite-borne laser communication system. The downlink intensity fluctuation is then simulated using a computer model that takes into account the effects of acquisition and tracking control, satellite attitude perturbation, and intensity fluctuation due to atmospheric turbulence. The simulation shows that when the tracking control-loop is closed, the major portion of the angular variation due to satellite attitude variation is corrected by the tracking control; scarcely any angular error in beam pointing remains.
