Satellite-based augmentation system

A Satellite-Based Augmentation System (SBAS) enhances the accuracy and reliability of satellite navigation systems, like GPS. It uses additional satellites to provide correction data, which helps improve positioning accuracy from about 10 meters to within a few centimeters. SBAS works by receiving signals from GPS satellites, monitoring their accuracy, and then sending correction signals to ground stations and users. This technology is important for applications such as aviation and land surveying, where precise location information is crucial for safety and efficiency.
