The European Geostationary Navigation Overlay Service (EGNOS) Safety of Life (SoL) Service is celebrating its tenth anniversary. Since it was declared operational in March 2011, the EGNOS SoL Service has been supporting civil aviation operations down to LPV (Localiser Performance with Vertical guidance) minima at airports across Europe.
The EGNOS SoL Service consists of timing and positioning signals intended for most transport applications in domains where lives could be endangered if the performance of the navigation system is degraded below specific accuracy limits. The SoL service is based on integrity data provided through the EGNOS satellite signals. With over 700 EGNOS-based procedures at 367 airports and helipads, the system increases safety, accessibility and efficiency for operators and pilots approaching airport and helipads in Europe. Accessible airports equal more commercial opportunities for airlines and new flight routes at a regional and international level, with minimum costs for ground infrastructure and its maintenance.
