Wideband Global SATCOM Satellite

WIDEBAND GLOBAL SATCOM SATELLITE
 
Mission

As the backbone of the U.S. military's global satellite communications, Wideband Global SATCOM Satellite (WGS) system provides flexible, high-capacity communications for the Nation's warfighters through procurement and operation of the satellite constellation and the associated control systems. WGS provides worldwide flexible, high data rate and long haul communications for the Department of Defense (DOD), governmental organizations and international partners.

Features
 
The WGS system is a constellation of highly capable military communications satellites that leverage cost-effective methods and technological advances in the communications satellite industry.  The WGS system is composed of three principal segments: Space Segment (satellites), Control Segment (operators) and Terminal Segment (users). Each WGS satellite provides service in multiple frequency bands, with the unprecedented ability to cross-band between the two frequencies onboard the satellite. WGS augments other satellites.

Each WGS satellite is digitally channelized and transponded. These characteristics provide a quantum leap in communications capacity, connectivity and flexibility for U.S. military forces and international partners while seamlessly integrating with current and future terminals. Just one WGS satellite provides more SATCOM capacity than the entire legacy Defense Satellite Communications System (DSCS) constellation.

Background
 
WGS provides essential communications services, allowing Combatant Commanders to exert command and control of their tactical forces, from peace time to military operations. Tactical forces will rely on WGS to provide high-capacity connectivity to the Defense Information Systems Network (DISN).

The on-orbit WGS constellation is comprised of multiple satellites in geosynchronous orbit.

The U.S. Space Force’s Space and Missile Systems Center is responsible for development, acquisition, fielding and sustainment of the WGS Program.
 
Space Delta 8’s 4^th Space Operations Squadron located at Schriever Air Force Base, Colo., operates WGS.

General Characteristics
 
Primary function: High-capacity military communications satellite
