Feasibility study of microsatellite laser communication pointing system based on SEEOR technology

Abstract

Satellite laser communication technology is a communication method that uses laser beam as information transmission carrier to transmit information data in space. It has many advantages such as large communication capacity, long transmission distance, high bandwidth, no spectrum permission, etc,widely used at present. The beacon light direction of its typical satellite laser communication system is realized by rough tracking servo turntable platform carrying optical components, so,there are a series of shortcomings such as turntable vibration, corner error and system inertia etc. Currently, a new technology, Non-Mechanical Beam Steering (NMBS) technology, in mid-wave infrared (MWIR) which has emerged, is expected to break through above shortcomings and provide possibilities for the transmission of beacon light in satellite laser communication. This paper focuses on the application of non-mechanical beam pointing technology in satellite laser communication system. We objectively analyzed the basic principles of the Non-Mechanical Beam Steering chip work, and the feasibility of using Non-Mechanical Beam Steering to transmit beacon light in satellite laser communication theoretically. It will open up a new way for the development of microsatellite laser communication technology in the future.
