Satellite Control Network

80:. These SOCs are staffed around the clock and are responsible for the command and control of their assigned satellite systems. The SOCs are linked to remote tracking stations (RTSs) around the world. Space vehicle checkout facilities are used to test launch vehicles and satellite platforms to ensure that the onboard systems operate within specifications. The RTSs provide the link between the satellites and the SOCs. A similar relationship exists for dedicated networks, which are outside the purview of the Satellite Control Network. RTSs around the world are needed to maintain frequent communications with the satellite. Without RTSs, the SOCs would only be able to contact a satellite when it came into the control center's view. Some satellites, especially those in geostationary orbit, never come within view of their control center. Each antenna at an RTS is referred to as a "side". Previously, Side A typically included a 60-foot-diameter (18 m) dish antenna. Side B typically included a 46-foot-diameter (14 m) antenna. At some sites, the B side included a 33-foot-diameter (10 m) antenna. Over time, however, as the network upgraded and/or replaced the antennas, the old conventions no longer apply. 465:, Seychelles; callsign INDI (closed in August 1996, after the Government of Seychelles attempted to "raise the rent" to more than $ 10 million/year). The Indian Ocean Tracking Station was located on the island of Mahe, the main island of the Seychelles archipelago. It had one 60-foot antenna. Its location was ideal for communicating with geosynchronous satellites over the Indian Ocean. The station was also geographically suited for acquiring realtime or near-realtime data from passes over areas to the north. In 1980, due to political instabilities of the island, the main processing computers were removed and relocated to Sunnyvale. These computers communicated with the IOS downlink and tracking equipment via a wideband (DSCS) communications link. IOS has been supplanted by Diego Garcia RTS. 56:. This involves continual execution of Telemetry, Tracking, and Commanding (TT&C) operations. In addition, the SCN provides prelaunch checkout and simulation, launch support, and early orbit support while satellites are in initial or transfer orbits and require maneuvering to their final orbit. The SCN provides tracking data to help maintain the catalog of space objects and distributes various data such as satellite ephemeris, almanacs, and other information. It was previously known as the Air Force Satellite Control Network (AFSCN) while under 704: 674: 495:; callsign PIKE. As of 2008, this site transitioned from an operational location to a testing facility, with operational support as possible. This site formally ceased operational support on 2 August 2012. It used to support various DoD satellites and previously included enhancement equipment that was used to support the Global Positioning System satellites. On 30 September 2014, the site was formally deactivated and closed. 400: 198:, Hawaii; callsign HULA. The Hawaii Tracking Station is located on the island of Oahu and also includes an ARTS side and an RBC side. The Hawaii Tracking Station is also undergoing a "hybridization" effort that will replace the old B-side ARTS system and upgrade the existing 60-foot antenna (previously the A-side). 314:
was planned to be completed in 2015. In May, 2013, the A-side antenna suffered a mechanical failure that prompted an early decommissioning. From that time, the site operated only with its B-side. Starting in 2014, the new C-side RBC installation got under way. This is the northernmost RTS, located at

In the late 1980s and early 1990s, the RTSs were modernized with the addition of the Automated Remote Tracking Station (ARTS) systems. The ARTS systems provided more responsive support and reduced the manpower required at each site through semi-automation. In addition to upgrading all the existing

Sunnyvale Control Station, callsign CUBE. Not a true tracking station, in that it had no direct downlink antenna. Instead, CUBE supported operations at TCS/Oakhangar and IOS/Seychelles, where main processing computers could not be located. CUBE had two 'sides', and so could support two satellite

As of 2010, the site includes three sides, two ARTS and an RBC. 191:; callsign GUAM. The Guam Tracking Station has two sides (one ARTS and one RBC) and is undergoing a "hybridization" upgrade that replaces the old A-side ARTS system with an RBC core electronics suite and upgrades the existing 60-foot antenna. 499:
There was a tracking station on Annette Island that is one of the Alaska islands far south east of the Alaska main land area and not too far north of Seattle Washington. It was built in the mid/late 1950s and closed in the early 1960s.

Beginning in 2004, an upgrade effort was started to replace the ARTS sites, which were already beyond their planned design life. The following sites have been upgraded to the RBC configuration, which includes a 13-meter 3-axis antenna:
