摘　　要：在微波波段实现了对卫星的通信和测控一体化技术，为了适应未来天基信息网络建设的需要，提出了一种高速激光数据传输与高精度激光测距一体化技术即激光统一系统。在激光通信的基础上，采用周期性伪码测距技术实现两颗卫星之间的距离测量。本文介绍了激光统一系统的系统组成，并分析存在的关键技术。研制了地面激光统一系统原理样机，通信速率达到了2．5Gbps，测距精度达到了2cm，并对未来激光统一系统的发展提出建议。The integrated technique of satellite communication and TY＆C is realized in microwave band. This paper presents a new integrated technique of high speed laser data communication and high precision laser ranging, namely unified laser system, to meet the requirements for future establishment of space - based information network. Based on laser communication, the distance between two satellites is measured by adopting peri- odic pseudo noise ranging technique. The paper introduces the system composition of unified laser system and analyzes its key techniques. The prototype of unified ground laser system is developed and its communication speed reaches 2.5Gbps and measurement precision reaches 2cm. The suggestions on future development in unified laser system are provided.
