Satellite-Terrestrial (Earth) Station Optical Communication

Abstract

The paper demonstrates the computation (design) of the laser beam power distribution emitted by Amsat P3D-like satellite towards the Earth surface. Amsat P3D satellite carries a laser transmitter which is used for laser signal detection research. The evaluation of the similar links availability based on the stationary FSO link parameters is presented. The special receiver, which utilizes an APD photodiode, was developed. This receiver operates in the photon counter mode. Special concept of the receiver provides detection of extremely low-level signal. The contribution includes the presentation of the performance of the receiver and its noise analysis as well.
