SBAS RECEIVERS

The receiver supports SBAS (satellite based augmentation systems) that conform to RTCA/DO-229C, such as WAAS, EGNOS, or MSAS. The receiver can use the WAAS (Wide Area Augmentation System) set up by the Federal Aviation Administration (FAA). WAAS was established for flight and approach navigation for civil aviation. WAAS improves the accuracy, integrity, and availability of the basic GPS signals over its coverage area, which includes the continental United States and outlying parts of Canada and Mexico. SBAS can be used in surveying applications to improve single point positioning when starting a reference station, or when the RTK radio link is down. SBAS corrections should be used to obtain greater accuracy than autonomous positioning, not as an alternative to RTK positioning. The SBAS system provides correction data for visible satellites. Corrections are computed from ground station observations and then uploaded to two geostationary satellites. This data is then broadcast on the L1 frequency, and is tracked using a channel on the BD9xx receiver, exactly like a GPS satellite. (en)
