Abstract

Laser space communication has obvious advantages in interstellar transmission，but the space environment will have a direct impact on laser communication system. The function of the analysis of space environment identity effectively could reduce and avoid the bug and invalidation produced by the overload to prolong the using span of effective load and increase the credibility of effective load, meanwhile it is also the main principle to design and research .This article summarizes the characteristics of vacuum space environment(Effect of vacuum outlet, Molecular contamination effect, Vacuum Mount, Cold welding effect, Heat radiation effect under vacuum), low temperature environment, background radiation (including space background radiation caused by thermal radiation, space background radiation caused by light noise). Space background radiation for the performance of space laser communication load is two aspects: one is the background of space radiation caused by thermal radiation, it mainly affects the satellite platform and payload of the thermal control design; Background spectrum caused by radiation and space, it will affect the space laser communication of the signal-to-noise ratio of the receiving unit, which affect the acquisition probability, tracking accuracy and error rate of communication, and particle radiation environment (Including total dose effects, single event effect), the plasma environment in five areas from the characteristics of space environment, for the problem of Space channel Influence the laser communication system performance. On this basis ,this article analysis the influence of space environment on the laser communication system with some examples, which will lay the foundation for the application of space laser communication system of our country.
