Currently, it supplements GPS by reporting on the reliability and accuracy of their positioning data and sending out corrections.

This roadmap should cope with legacy and new missions:[7] In 2021, following Brexit, the United Kingdom withdrew regulatory approval for EGNOS, and aircraft pilots were no longer permitted to use the system.

[8] Similar to WAAS, EGNOS is mostly designed for aviation users who enjoy unperturbed reception of direct signals from geostationary satellites up to very high latitudes.

To address this problem, ESA released in 2002 SISNeT,[17][18] an Internet service designed for continuous delivery of EGNOS signals to ground users.

Support segment: In addition to the above-mentioned stations/centres, the system has other ground support installations involved in system operations planning and performance assessment, namely the Performance Assessment and Checkout Facility (PACF) and the Application Specific Qualification Facility (ASQF) which are operated by the EGNOS Service Provider (ESSP).

This space segment configuration provides a high level of redundancy over the whole service area in the event of a failure in the geostationary satellite link.

Currently, EGNOS compatible receivers are available for such market segments as agriculture, aviation, maritime, rail, mapping/surveying, road and location based services (LBS).

[24] As of September 2018 LPV (Localizer performance with vertical guidance) landing procedures, which are EGNOS-enabled, were available at more than 180 airports across Europe.
