, WAAS, EGNOS) Augmentation Improves accuracy for aviation and maritime navigation GBAS Augmentation Provides precision approach guidance for aircraft QZSS (Japan) Regional/Global Enhances GPS accuracy and reliability in the Asia-Oceania region. Each satellite in the constellation carries a highly precise atomic clock and continuously broadcasts its orbital parameters and the exact time the signal was transmitted.
Regional and Augmentation Systems Complementing the global networks are regional and augmentation systems that enhance accuracy, integrity, and availability. Global systems are designed to provide coverage across the entire planet, whereas regional systems optimize accuracy and performance within specific continents or countries.

"Navigation" refers to the capability of determining a receiver's position, course, and speed to facilitate movement from one location to another. Global Navigation Satellite System, or GNSS, represents the collective infrastructure of space-based radio-navigation services that provide autonomous geospatial positioning with global coverage.
