The Deep Space Network (DSN) supports NASA and non-NASA missions that explore the furthest points of our solar system. The DSN has three ground stations located approximately 120 degrees apart on Earth.
The Near Earth Network provides telemetry, commanding, ground-based tracking, data and communications services. The NEN provides these services to customers with satellites in low Earth orbit, geosynchronous orbit, highly elliptical orbit, lunar orbit and missions with multiple frequency bands.
The Space Network consists of a constellation of geosynchronous satellites named the Tracking and Data Relay Satellite and ground systems that schedule, command and control the relay system of satellites.
The SCaN Integrated Network will provide standard services, components and interfaces to all missions.
