Abstract

Free-space optical communication offers an attractive alternative for transferring high- bandwidth data over RF (Radio Frequency) signals. However, satellite vibration is the major pointing error. Without compensating for it, the optical communication terminal cannot achieve accurate and stable links. The effect of this phenomena leads to the misalignment between the transmitter and the receiver, decrease in the received signal and increase in BER (Bit Error Rate). With this in mind, this paper examines the effect of satellite vibration on optical link and develops a BER model that takes the satellite vibration into account. Then, a feed- forward vibration compensation model under fine tracking mode is designed to decrease this residual jitter influences. The results show that the proposed method is simple and effective, and the vibration amplitude can be decreased greatly.
