摘　　要：测控网具备网际互操作能力可以实现资源共享,提高设备利用率,降低研制、操作与维护成本和风险,已成为测控网的发展趋势。美国在天基网、地面测控网、深空网和军用测控网之间利用空间链路扩展(SLE)设备进行了成功的互操作演示验证,各国航天局也在各自的航天任务中使用SLE业务实现互操作支持。文中介绍了SLE业务的体系结构与作用,概述了SLE业务在各国的应用现状。Consultative Committee for Space Data System （CCSDS） Space Link Extension （SLE） services enable the TT＆C assets in ground and space segment of space agencies to interoperate in order to share resource, reduce development, operation and maintenance costs and risk, and become the developing trend of TT＆C network. The CCSDS SLE Transfer Service has been demonstrated in interoperability among NASA＇ s Ground Network （GN）, Space Network （SN）, JPL＇s Deep Space Network （DSN） and DOD＇s Air Force Satellite Control Network. SLE services have been used in many space missions in space agenies in the world. This paper introduces the architecture and roles of SLE services, and summarizes the application in foreign countries.
