SBAS (Satellite-Based Augmentation System)

SBAS (Satellite-Based Augmentation System) enhances global navigation satellite systems like GPS by providing additional corrections and integrity information. It improves positioning accuracy, reliability, and trustworthiness, especially for critical applications like aviation and maritime navigation. SBAS uses a network of ground stations that monitor satellite signals, generate correction data, and transmit it via geostationary satellites. This system helps users determine their position more precisely and confidently, ensuring safety and efficiency in navigation and various location-based tasks. Examples include systems like WAAS in North America and EGNOS in Europe.
