Space-based augmentation systems (SBAS)

Space-based Augmentation Systems (SBAS) are advanced satellite systems that improve the accuracy and reliability of Global Navigation Satellite Systems (GNSS) like GPS. They use a network of ground stations that monitor satellite signals and send correction data back to satellites. This helps reduce errors caused by atmospheric conditions and other factors, allowing for precise location information. SBAS is particularly useful in aviation, maritime navigation, and land surveying, where accurate positioning is crucial for safety and efficiency. By enhancing GNSS signals, SBAS ensures users receive higher-quality location data.
