摘　　要：基于商用计算机技术和高速网络通信技术发展的e—VLBI技术在数据记录系统、数据格式、传输协议等方面发展迅速，并己得到广泛应用。中国VLBI网所属观测站及数据中心通过通信网络的连接，成为具备实时e—VLBI能力的测量系统，在探月工程历次任务中，实现了对观测数据的快速可靠采集、传输和处理，为月球探测器提供了重要的实时测定轨数据。为适应未来天体物理、天体和大地测量宽带科学观测需求，e—VLBI面临新的机遇及挑战。Based on commercial computer products and high-speed network, real-time e-VLBI has developed rapidly in the data recording system, data format standards and transport protocols in the recent decades and has been widely used in VLBI observations. Connected with high-speed network, Chinese VLBI network is able to perform real-time e-VLBI observation. In a series mission of China＇s lunar exploration project, e-VLBI system has proved its ability of fast acquisition, reliable transmission and accurate data processing, and has provided important data for the real-time positioning of the spacecraft. To meet the requirement of radio astronomy and geodesy in the future, we summarize the challenge and the development tendency of VLBI technology.
