The design of inter-satellite laser link interface model based on standardized transfer mode

It has a larger impact on system performance, transmitting the different type data simultaneously when exchanging inter-satellite data. Inter-satellite laser link interface model (ILIM) is proposed to unify the transfer mode of optical satellite network and improve the data transmission efficiency. In inter-satellite communication, the satellite node has the downside of inefficient. Therefore, data frame adaptation unit is designed to integrate the data from different sources. It is feasible to add Link transmission processing unit (LTU) that tries to avoid reducing system efficiency which cause by random error in spatial channels, enhances the reliability of the laser link,and analyzes the applicability of ILIM for Relay Satellite System and Distributed Satellite System. The results show that the transmission efficiency promotes 34.04% and the system error correction performance improves 3.01dB after applying ILIM.
