The European Geostationary Navigation Overlay Service, is a Satellite-Based Augmentation System (SBAS) that improves the accuracy and provides integrity to the GPS Signal over most of Europe.The EC owns and manages the EGNOS system. ESA is the EGNOS design agent under a delegation agreement with the EC. Similar services are provided in North America by the Wide Area Augmentation System (WAAS), in Japan by the Multifunctional Satellite Augmentation System (MSAS) and in India by the GAGAN System. Other similar Satellite Based Augmentation Systems (SBAS) are under study or development in other regions of the world. It is Europe's first venture into satellite navigation and a major stepping-stone towards Galileo, Europe's own global satellite navigation system for the future. Starting from 1st January 2014, EGNOS will be managed by the European GNSS Agency (GSA).
