—A natural development in the space communication is the free space laser communication. The free space laser communication has greater advantage over traditional Radio Frequency (RF) communication. Some of the advantages are high data rate, low probability of detection and minimum interception. The major limitation of this optical communication is the noise introduced by the mechanical vibration of the satellites. This kind of vibration causes pointing problem and affects the performance of the inter-satellite link in terms of bit error rate. Hence a perfect tracking system is required for transmitting and receiving satellite. In this paper, a novel method to improve tracking system has been introduced. It has been shown that the vibration effects can be reduced to an acceptable level and hence the bit error rate can be reduced by using a feed forward compensation technique. The improvement in Bit Error Rate (BER) has also been presented in this paper.
