Defense Meteorological Satellite Program
The Defense Meteorological Satellite Program (DMSP) has been collecting weather data for U.S. military operations for more than five decades and provides assured, secure global weather and space weather data to support Department of Defense (DOD) operations.
Defense Satellite Communications System
Defense Satellite Communications System (DSCS) constellation provides long haul communications to users worldwide through contested environments.
Defense Support Program Satellites
U.S. Space Force-operated Defense Support Program (DSP) satellites are a key part of North America's early warning systems. In their 22,300-mile, geosynchronous orbits, DSP satellites help protect the United States and its allies by detecting missile launches, space launches and nuclear detonations.
Geosynchronous Space Situational Awareness Program
Geosynchronous Space Situational Awareness Program (GSSAP) satellites are a space-based capability operating in the near-geosynchronous orbit regime supporting U.S. Space Command space surveillance operations as a dedicated Space Surveillance Network (SSN) sensor.
Global Broadcast Service
Global Broadcast Service (GBS) operates as a one-way wideband transmission broadcast, supporting timely delivery of data and video products for mission support and theater information transfer. GBS provides service to over 1000 receive suites deployed world-wide supporting the Department of Defense and other governmental organizations and agencies.
Global Positioning System
The Global Positioning System (GPS) is a constellation of orbiting satellites that provides position, navigation, and timing data to military and civilian users globally. The system is operated and controlled by Space Delta 8, located at Schriever Air Force Base, Colo.
Ground-Based Electro-Optical Deep Space Surveillance
The Ground-Based Electro-Optical Deep Space Surveillance (GEODSS) System plays a vital role in tracking deep space objects. More than 2,500 objects, including geostationary communication satellites, are in deep space orbits varying in altitude from 10,000 to 45,000 kilometers from earth.
Milstar Satellite Communications System
Milstar provides the President, Secretary of Defense and the U.S. armed forces with assured, survivable satellite communications (SATCOM) with low probability of interception and detection, and is designed to operate through contested environments.
PAVE PAWS Radar System
PAVE Phased Array Warning System (PAWS) Radars are maintained by the U.S. Space Force. These radars are capable of detecting Submarine Launched Ballistic Missile (SLBM) attacks and conducting general space surveillance and satellite tracking. PAVE is a military program identification code.
Perimeter Acquisition Radar Attack Characterization System
The Perimeter Acquisition Radar Attack Characterization System (PARCS) is a single-faced, multi-function, UHF-Band, phased-array radar located at Cavalier Air Force Station, N.D.
