This paper introduce the research significance and critical technology about the laser communication between plane and satellite, summarizes the development on such technology domestic and aboard, studies on the theory which exterior environment and atmosphere have an effect on laser according to research needs, meanwhile, according to various parameters of laser communicate process, simulated researches the integral process. Researchers can observe laser goes through transmit aerial, atmospheric , free space loss, background light radiation and other external environment with all kinds of diagram tools. From that we can conclude the laser position and energy distribution when the laser reaches the satellite. So that, we can value the whole communication process and set up simulation model to further analysis the influence of external environment on laser communication.
