Laser communication system is built to satisfy the urgent need of information transmission of the earth observation system and space-based information in high resolution and the need of high-speed transmission rate of distribution system. Laser communication system makes use of laser frequency band, takes laser as information carrier and transmits information by the modulation of laser pulse and thus achieves information exchange. And to achieve information exchange, we must solve the tracking and pointing technical problem because this is the guarantee condition of successful laser communication and key technology to improving communication performance. This article firstly introduces the development of space laser communication technique at home and abroad in recent years and the introduces the research situation of several key technology in space laser communication tracking and pointing system to provide guidance to the research on space laser communication system and tracking and pointing technology.
