| Abstract: | Free-space optical communication between satellites networked together can make possible high-speed communication between different places on earth. Some advantages of an optical communication system in free space are (1)smaller size and weight,(2)less transmitter power,(3)larger bandwith,and(4)higher immunity to interference. The pointing from one satellite to another is a complicated problem due to the large distance between the satellite, the narrow beam divergence angle, and vibration of the pointing system. Such vibration of the transmitted beam in the receiver plane decreases the average received signal,which increase the biterr or rate, In this paper, seven approaches to overcome the problems are studied. |
