At the moment, information transmission is mostly transmitted by adopting the traditional RF data link among the aviation platforms. Whereas the RF data link remains a lot of the problems that transmission rate is low, RF resource is limited and easy in interference, and easy to be intercepted. Such inadequate resources are hardly to meet the needs of the development of space exploration, the highspeed transmission, the interconnection and sharing of the spatial information transmission and the expanding application in the military field. and development demanding to the highspeed data transmission and information security of the aviation platform. Therefore, by using the characteristics of the aviation platform in the aspects of information acquisition, transmission and distribution, a highspeed transmission, a safe and reliable air platform communication link is established, and the networking application of the aviation platform is further realized, which is the basis for ensuring the safe and reliable transmission of the spatial information network data. highspeed transmission of data information in military fields such as airspace security, longrange combat and command and control. Optical communication among aviation platforms is characterized by the high speed, large bandwidth, antiinterference, good confidentiality, miniaturization of terminal, and so on. Such an optical communication has advantages in reliable transmission of aviation platform and military confidentiality applications,and can not only break through the restrictions of ground command and control center on aviation platform, but also effectively improve the technical disadvantages of traditional RF data links in bandwidth, antielectromagnetic interference and stealth transmission. The mentioned above subject is an important research field and development direction of future spatial information network to use aviation optical communication technology to realize highspeed data transmission between machines in the future, and to construct aviation information network with interconnection and information sharing.
