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.
