Air Force Satellite Control Facility
The United States Air Force's Air Force Satellite Control Facility (AFSCF) was a space command and control unit located at Onizuka AFS, California. It has the distinction of being heavily involved in the world's first reconnaissance satellite program, CORONA. Due to geological hazards (i.e. earthquakes), and the terrorism threat from its proximity to a major transportation link (California Highway 101), the facility's command and control functions were moved to Schriever AFB, Colorado. History The Air Force Satellite Control Facility (AFSCF) was originally activated at Los Angeles AFS, California on 18 Jun 1965.AFHRA FOIA Request 2009-02203, 21 July 2009 It was first assigned to the Space Systems Division of Air Force Systems Command, with later moves under the Space and Missile Systems Organization, and Space Division organizations.

National Reconnaissance Office
The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government, and provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the NSA, imagery intelligence (IMINT) to the NGA, and measurement and signature intelligence (MASINT) to the DIA. NRO is considered, along with the Central Intelligence Agency (CIA), National Security Agency (NSA), Defense Intelligence Agency (DIA), and National Geospatial-Intelligence Agency (NGA), to be one of the "big five" U.S. intelligence agencies. The NRO is headquartered in Chantilly, Virginia, south of the Washington Dulles International Airport. The Director of the NRO reports to both the Director of National Intelligence and the Secretary of Defense. The NRO's federal workforce is a hybrid o ...

Space Test Program
The Space Test Program (STP) is the primary provider of spaceflight for the United States Department of Defense (DoD) space science and technology community. STP is managed by a group within the Advanced Systems and Development Directorate, a directorate of the Space and Missile Systems Center of the United States Space Force. STP provides spaceflight via the International Space Station (ISS), piggybacks, secondary payloads and dedicated launch services. Past activities STP has actually been in existence for 50 years as of 2019, with several thousand launches it has been responsible for. For example, the initial experiments that led to the modern Global Positioning System (GPS) satellite constellation were STP-launched projects. 2001 During August 2001, STP conducted two successful activities using the Space Shuttle and ISS. STS-105 delivered and successfully deployed the Materials International Space Station Experiment (MISSE) externally on the ISS. MISSE was a passive mat ...

Fleet Satellite Communications System
FLTSATCOM (also FLTSAT) is a satellite communication system of the U.S. Space Force which was used for UHF radio communications between ships, submarines, airplanes and ground stations of the Navy. Most of the transponders on these satellites were simple repeaters with no authentication or control over what they retransmitted. FLTSATCOM Altogether eight satellites were launched from 1978 to 1989 by Atlas-Centaur rockets into geostationary orbit. The system became operational in 1981. The satellites were manufactured by TRW. The solar array of each satellite had a span of over 13.2 m. A special characteristic was a UHF transmit antenna reflector 4.9 m in diameter. Each satellite had 12 transponders, which worked in the UHF range from 240 - 400 megahertz. Additionally FLTSATCOM 7 and 8 included an experimental EHF transponder built by Lincoln Laboratory intended to test the MILSTAR ground terminals. The first seven satellites each had a launch mass of 1884 kg and the remain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft was lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Angeles AFB
Los Angeles Air Force Base (LAAFB) is a United States Space Force Base located in El Segundo, California. Los Angeles Air Force Base houses and supports the headquarters of the United States Space Force's Space Systems Command (SSC), which was established on Aug. 13, 2021. The center manages research, development and acquisition of military space systems. Space Base Delta 3 provides support functions for the base. History Los Angeles Air Force Base traces its history back to the Air Research and Development Command's Western Development Division, which was activated on 1 July 1954 in Inglewood, not far from the current base. In 1961 the Air Force developed a plan to consolidate its Space Systems Division and the Research and Development (R&D) Center of The Aerospace Corporation, which was created in 1960 to support Air Force space programs. The plan involved the acquisition of two pieces of real estate adjoining the R&D Center. An aircraft plant owned by the Navy, at the ...

Sunnyvale AFS
Onizuka Air Force Station or Onizuka AFS was a United States Air Force installation in Sunnyvale, California, at the intersection of State Route 237 and North Mathilda Avenue. It was operational from 1960 to 2010. Its distinguishing feature was Building 1003, known locally as the Blue Cube or simply the "Cube" given its size, color, and lack of windows. The station's other distinguishing features were its three primary parabolic dish antennas used for communication with remote tracking stations used to control military satellites; these antennas were named Sun East, Sun West, and Sun 3. History In the United States space program's formative stages, Air Force Systems Command (AFSC) contracted with the Philco Ford division of Ford Motor Company to provide interim operational facilities at its Palo Alto, California location. Operations commenced in the late 1950s. By 1958, the US Air Force sought a permanent home with larger facilities. Ultimately, the Air Force purchased roughly ...
