The EGNOS Safety of Life (SoL) assisted service for Maritime Users (ESMAS) is the first Satellite-based Augmentation System (SBAS) service tailored to maritime users. ESMAS improves the performance of GPS, and in the future, of Galileo, by augmenting satellite signals with corrections and information on signal integrity. It thus helps users achieve the accuracy and integrity required for navigation at sea, whether on oceans and in coastal waters or during harbour approaches and entrances.
Other EGNOS services
EGNOS Data Access Service (EDAS) provides ground-based access to EGNOS data through the Internet in near real-time. With a controlled access system, EDAS allows users to connect to a variety of services which provide raw GPS, GLONASS, and EGNOS data, plus EGNOS augmentation messages.
EGNOS Open Service (OS) provides free and accessible use of EGNOS services to any user equipped with a GPS/SBAS-compatible receiver.
The EGNOS Safety of Life (SoL) Service improves the accuracy and reliability of GPS, and soon, Galileo, and provides timely alerts when navigation performance degrades.
