Welcome to the
EGNOS  User Support
The European Geostationary Navigation Overlay Service (EGNOS) provides an augmentation service to the Global Positioning System (GPS) Standard Positioning Service (SPS). Presently, EGNOS augments GPS using the L1 (1575.42 MHz) Coarse/Acquisition (C/A) civilian signal function by providing correction data and integrity information for improving positioning, navigation and timing services over Europe.

The EGNOS User Support website managed by ESSP is the main entry point for EGNOS related information, including performance (real time, historical and forecast) and other support and adoption material for the three EGNOS Services (Safety of Life Service, Open Service and EDAS).
