Each reference station in the Wide Area Augmentation System includes three GPS antennas. The coordinates of each antenna, along with its elevation, are listed below. The coordinates of each antenna, along with its elevation, are listed below.
The Wide Area Augmentation System (WAAS) is an air navigation aid developed by the Federal Aviation Administration to augment the Global Positioning System (GPS), with the goal of improving its accuracy, integrity, and availability. Essentially, WAAS is intended to enable aircraft to rely on GPS for all phases of flight, including approaches ...
Stations used to generate differential corrections of Global Positioning System fixes for points in North America, transmitted over the Wide Area Augmentation System. Pages in category "WAAS reference stations"
In the US, GBAS was previously known as the Local-area augmentation system while a SBAS with a ground references network providing GPS corrections is called WAAS. In the US, there were more WAAS LPV approaches reaching 200 ft (61 m) than Cat. 1 ILS approaches by March 2018. 1 GBAS costs $3–4 million; and $700,000 more for Cat. 2.
DGPS Reference Station (choke ring antenna)A reference station calculates differential corrections for its own location and time. Users may be up to 200 nautical miles (370 km) from the station, however, and some of the compensated errors vary with space: specifically, satellite ephemeris errors and those introduced by ionospheric and tropospheric distortions.
Ground stations determine the accuracy of the satellite navigation systems data and transfer it to the geostationary satellites; users may freely obtain this data from those satellites using an EGNOS-enabled receiver, or over the Internet. One main use of the system is in aviation.
StarFire is a wide-area differential GPS developed by John Deere's NavCom and precision farming groups. StarFire broadcasts additional "correction information" over satellite L-band frequencies around the world, allowing a StarFire-equipped receiver to produce position measurements accurate to well under one meter, with typical accuracy over a 24-hour period being under 4.5 cm. StarFire is ...
Awarua Satellite Ground Station (formerly Awarua Tracking Station) is an Earth station built initially to support the European Space Agency Ariane 5 ES ATV (Automated Transfer Vehicle) launch campaigns. It was established by Venture Southland in 2007.
