The already available basic navigation signal provided by EGNOS is an open and free service available for everyone. It provides Europeans with unprecedented positioning precision by improving the accuracy of the USA’s Global Positioning System (GPS).
The continuous monitoring of the EGNOS signal shows that it improves the accuracy of GPS to within one to two metres and is available more than 99 percent of the time.
The European Commission has confirmed that this level of performance is available for the long term and that the signal can be used without any charges. Receiver manufacturers and application developers are able to provide their customers with the benefits of these GPS performance improvements by adding EGNOS capability to their products. No authorisation or receiver-specific certification is required.
