EGNOS, or the Euro Geostationary Navigation Overlay Service is a GPS augment developed Europe to network together air-based, ground-based and satellite based GPS stations to triangulate precise positions from all of them, enabling a reliable GPS fix in three dimensions rather than just two.

EGNOS corrects for GPS signal errors caused by ionospheric disturbances, timing, and satellite orbit errors, giving accuracy in X, Y, and Z axis accurate to within 3 metres, in real-time. This makes it ideal for fast-moving objects such as planes, to track their precise location constantly.

As a nice side-effect, EGNOS is able to report on satellite conditions. If one drifts out of orbit, the system picks this up immediately as its GPS telemetry for other objects disagrees with the rest of the network stations.

EGNOS is compatible with basic GPS signal structure.

Whilst EGNOS is only applicable for the European landmass, other geographic areas are developing their own systems, which are inter-compatible. . In Asia, it's the Japanese Multi-Functional Satellite Augmentation System (MSAS), while the US has the Wide Area Augmentation System (WAAS)
