The Space Network (SN) consists of a ground segment and a space segment. The ground segment has two facilities located in New Mexico and one located on Guam Island. The space segment consists of the Tracking and Data Relay Satellites (TDRS).

The current ground system of equipment for the Space Network is approaching thirty years old and is becoming more difficult to operate, maintain and replace parts. As newer systems replace the older ones, it becomes increasingly difficult for the older systems to interface with the new ones and function at full capacity.

Therefore, the Space Communications and Navigation (SCaN) office has initiated a sustainment effort named the Space Network Ground Segment Sustainment (SGSS) project. SGSS is tasked with defining an architecture map to upgrade technology and sustain the SN operations for at least 25 years. The mission of SGSS is to: implement flexible and extensible ground segment and maintain the high level of service in the future.
