In the procedure of inter-satellite data exchange,the different types of simultaneous data transmission have a serious impact on system performance.Inter-satellite laser link interface model (ILIM)is proposed to unify the transfer mode of optical satellite network and to improve the data transmission efficiency.In inter-satellite communication,the node satellite has low retransmission efficiency.Therefore,data frame adaptation unit is designed to integrate the data from different sources.Link transmission processing unit (LTU)is added to reduce the influence of system performance which cause by random error in spatial channels,and it can enhance the reliability of the laser link transmission.The applicability of ILIM for Relay Satellite System and Distributed Satellite System is studied.The results show that the transmission efficiency is improved by 49.93% and the system error correction performance is heightened by 3.01 dB after applying ILIM.
