Satellite Ground Systems

Connecting Satellites to Earth

General Dynamics has been a leading provider of satellite ground systems solutions for more than 30 years. Our experience and constant innovation bring the value of satellite systems in space down to the users on Earth. These solutions include:

Mobile User Objective System

The Mobile User Objective System (MUOS) is the U.S. Navy’s next-generation satellite communications system that provides simultaneous voice, video and data communications for U.S. Armed Forces anytime and anywhere in the world. General Dynamics leads the deployment of the MUOS ground system, which includes four ground station facilities positioned around the globe to assist in the management and operation of the orbiting satellites.

Space Fence

General Dynamics is designing and constructing the ground structures for the U.S. Air Force's Space Fence program, which will expand the range of current radars used to track space junk while protecting astronauts and satellites from dangerous collisions. The new advanced ground-based radar system that will enhance the way the U.S. detects and tracks orbiting objects in space, preventing space-based collisions.

Space Network Ground Segment Sustainment

General Dynamics is the prime contractor for NASA’s Space Network Ground Segment Sustainment (SGSS) project that is modernizing the space agency’s ground infrastructure systems for their Space Network, and provides for continuous technology insertion and system upgrades for the next 25 years.

Deep Space Network 

NASA's Deep Space Network is an international collection of antennas that support NASA's spacecraft missions as well as radar and radio observatories that explore the solar system and universe. Originally designed by JPL and built by General Dynamics, the antennas enable the Deep Space Network to communicate with existing flight missions such as the Mars Exploration Rovers, Spitzer Space telescope, Saturn explorer Cassini, as well as support future NASA space missions.

Tracking and Data Relay Satellite System

The Tracking and Data Relay Satellite System or TDRSS is NASA’s network of specialized communications satellites that orbit 22,300 miles above the Earth. General Dynamics has supported TDRS program for 30+ years through our work in helping NASA operate, upgrade and maintain the ground system terminals.
