CCSDS Space Link Extension (SLE) Services enable the ground segment assets of space agencies to interoperate, allowing for ground stations and space data users to interact without the need for ad hoc, complicated gateways designed specifically for each new mission. Their goal is to reduce the development, management, and operational costs of providing cross support between space organizations for exchange of tracking, telemetry, and command (TT&C) data. SLE services are actively supporting over a dozen spacecraft, with many more planned over the next few years. This paper first presents an overview of the underlying SLE architecture, as defined in the SLE Reference Model. The SLE data transfer services, which move data between mission facilities and ground stations are defined, along with the management services that enable missions to make requests for ground station services. Next, up-to-date status of the testing, prototyping, and implementation of SLE services over the past few years is presented, as well as plans for adoption of SLE services by a number of space networks and space mission organizations. Finally, efforts to adapt SLE services to support legacy missions are briefly described.Sponsors
