Wide Area Augmentation System (WAAS)

The Wide Area Augmentation System (WAAS) enhances the accuracy and reliability of GPS signals in North America. It uses a network of ground stations to monitor satellite signals, correcting errors caused by atmospheric conditions and other factors. These corrections are transmitted to geostationary satellites, which relay the enhanced data back to GPS receivers. As a result, WAAS significantly improves positioning accuracy to within a few meters, making it essential for applications like aviation, land surveying, and geolocation services. It helps users obtain precise location information, improving safety and efficiency in various industries.
