EGNOS vs Sofia VAC

The EGNOS application is a user-friendly tool designed to provide comprehensive access to information about the European Geostationary Navigation Overlay Service (EGNOS). It enables users to monitor real-time, historical, and forecasted performance data, access official EGNOS documentation, and explore guidelines and support materials tailored for different application domains, such as aviation, maritime, and land-based navigation. As Europe’s satellite-based augmentation system (SBAS), EGNOS enhances the accuracy, reliability, and integrity of GNSS signals, ensuring safer and more precise navigation. This is particularly crucial for sectors that require high levels of accuracy and safety, such as aviation. The EGNOS application serves as a gateway to key EGNOS services—Open Service (OS), Safety of Life (SoL), EGNOS SoL assisted service for Maritime Users (ESMAS) and EGNOS Data Access Service (EDAS)—helping users stay informed and maximize the benefits of EGNOS technology.
