An ATC ground station consists of two radar systems and their associated support components. The most prominent component is the PSR. It is also referred to as skin paint radar because it shows not synthetic or alpha-numeric target symbols, but bright (or colored) blips or areas on the radar screen produced by the RF energy reflections from the target's "skin."
A satellite whose orbital period is an integer fraction of a day (e.g., 24 hours, 12 hours, 8 hours, etc.) will follow roughly the same ground track every day. This ground track is shifted east or west depending on the longitude of the ascending node, which can vary over time due to perturbations of the orbit. If the period of the satellite is ...
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC is to prevent collisions, organize and expedite the flow of traffic in ...
The Diego Garcia Station has two sides (as of 2010) to provide enhanced tracking for the Satellite Control Network users. This site also includes a GPS Ground Antenna site. Guam Tracking Station (GTS), Guam; callsign GUAM. The Guam Tracking Station has two sides (one ARTS and one RBC) and is undergoing a "hybridization" upgrade that replaces ...
A U.S. Air Force E-8C Joint STARS, in flight. Airborne ground surveillance (AGS) refers to a class of military airborne radar system (Surveillance aircraft) used for detecting and tracking ground targets, such as vehicles and slow moving helicopters, as opposed to Airborne early warning and control, whose primary role is detecting and tracking aircraft in flight.
The Ground/Air Task Oriented Radar (G/ATOR) is a single material solution for the mobile Multi-Role Radar System and Ground Weapons Locating Radar (GWLR) requirements. It is a three-dimensional, short/medium-range multi-role radar designed to detect unmanned aerial systems, cruise missiles, air-breathing targets, rockets, artillery, and mortars.
As with any ground-based optical system, cloud cover and local weather conditions directly influence its effectiveness. GEODSS system can track objects as small as a basketball more than 20,000 miles (30,000 km) in space or a chair at 35,000 miles (56,000 km), and is a vital part of USSPACECOM's Space Surveillance Network.
Conceptual of the ADS-B system, illustrating radio links between aircraft, ground station and satellite. Automatic Dependent Surveillance–Broadcast (ADS-B) is an aviation surveillance technology and form of electronic conspicuity in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts its position and other related data, enabling it ...
