With the inactivation of the San Francisco Air Defense Sector at Beale in 1963, [specify] Mill Valley CDTS data was transmitted to Adair AFS, Oregon (DC-13). GATR R-18 was taken over [when?] by the 666th RADS as OL-A. In 1964 an AN/FPS-26A height-finder radar replaced the AN/FPS-6 and the AN/FPS-6B was modified to an AN/FPS-90.
The AFS is provided by voice and data networks, including AFTN, AMHS and CIDIN. [3] However, any aeronautical radiocommunication between specified fixed points belongs – in accordance with article 1.20 of the International Telecommunication Union's (ITU) Radio Regulations (RR) – to the Fixed service.<ref>ITU Radio Regulations, Section IV.
The Air Force Satellite Control Facility (AFSCF) was originally activated at Los Angeles AFS, California on 18 Jun 1965. [1] 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.
The facility's Air Route Surveillance Radar Model 1E with an ATCBI-6 beacon interrogator system are operated by the FAA [3] and provide sector data to North American Aerospace Defense Command. The site provided Semi-Automatic Ground Environment data to the 1959-66 Norton AFB Direction Center for the USAF Los Angeles Air Defense Sector.
The Coordinate Data Transmitting Set (CDTS) (AN/FST-2) at the main site converted each radar return into a digital word which was transmitted by the GATR via microwave to the Control Center. During 1961 Ajo AFS joined the Semi Automatic Ground Environment (SAGE) system, feeding data to DC-21 at Luke AFB, Arizona.
This is a list of GIS data sources (including some geoportals) that provide information sets that can be used in geographic information systems (GIS) and spatial databases for purposes of geospatial analysis and cartographic mapping. This list categorizes the sources of interest.
The AN/FSQ-7 Combat Direction Central, referred to as the Q7 for short, was a computerized air defence command and control system. It was used by the United States Air Force for ground-controlled interception as part of the Semi-Automatic Ground Environment network during the Cold War.
The World Wide Web is an information system that uses the internet to host, share, and distribute documents, images, and other data. [33] Web GIS involves using the World Wide Web to facilitate GIS tasks traditionally done on a desktop computer, as well as enabling the sharing of maps and spatial data. [7]
