Near Earth Network

The Near Earth Network (NEN, formerly GN or Ground Network) provides orbital communications support for Near-Earth orbiting customer platforms via various NASA ground stations.

NASA's NEN consists of ground stations in:

Also under contract are operators at Svalbard Satellite Station, Norway; Poker Flat Research Range and the Alaska Satellite Facility (ASF) in Fairbanks, Alaska; Santiago, Chile; South Point, Hawaii; North Pole, Alaska; and Dongara, Australia. Additionally, the MILA and Wallops stations provide pre-launch, launch, and landing communications support for the Space Shuttle program. The NEN and SN combined were previously referred to as the Spaceflight Tracking and Data Network (STDN).[1]

Authority and responsibility

The NEN falls under NASA's SOMD (Space Operations Mission Directorate), interoperating with the SCaN Program offices. The Goddard Space Flight Center Ground Network Project has responsibility for maintaining the NEN, as well as implementing the Satellite laser ranging (SLR) Network.

Support for Constellation

The NEN was slated to support the Constellation Program, including the Ares launch vehicle, NISN (NASA Integrated Services Network), FDF (Flight Dynamics Facilities), KSC Launch Control Center, and the Constellation Mission Control Center (MCC). Constellation has since been canceled.
