GAGAN India: GPS-Aided GEO Augmented Navigation, or GAGAN, was developed by the Indian Space Research Organization and Airport Authority of India. MSAS Japan:The Multi-Functional Satellite Augmentation System, or MSAS, is operated by the Japan Civil Aviation Bureau, a division of the Ministry of Land, Infrastructure, and Transport. Development for WAAS began in 1994.ĮGNOS European Union: European Geostationary Navigation Overlay Service, or EGNOS, was developed by the European Space Agency. WAAS United States, Canada, Mexico: Wide Area Augmentation System, or WAAS, is operated by the United States Federal Aviation Administration. Some receivers can apply SBAS corrections with additional techniques to achieve sub-meter or better accuracy. Using SBAS, users can achieve an accuracy of two meters or better. GNSS is normally accurate to around five meters. These SBAS corrections – called deviation corrections – allow GNSS receivers to more accurately and reliably determine their position. Corrections to the errors are sent to geostationary satellites and broadcast throughout the region. Any discrepancy is determined to be an error. To calculate GNSS position errors, GNSS data from satellites are compared against the precisely documented locations of each land-based monitor.
Each of these errors causes delays in timing, which result in position errors for a receiver. SBAS uses stationary land-based GNSS monitors to calculate GNSS position errors caused by atmospheric and ionospheric disturbances, satellite orbit errors, and inaccurate clocks. The increased accuracy is critical for aviation and is widely used by the geospatial industry for increased accuracy in navigation and mapping. To calculate GNSS position errors, GNSS data from satellites are compared. SBAS is a regional network of ground and satellite system that works to boost the accuracy and dependability of GPS and GNSS data. SBAS uses stationary land-based GNSS monitors to calculate GNSS position errors caused by atmospheric and ionospheric disturbances, satellite orbit errors, and inaccurate clocks. SBAS stands for satellite-based augmentation system. Map of the locations with SBAS coverage What does SBAS stand for?
