EGNOS Performance and Operational Implementation status

This document provides an overview of the EGNOS performance and operational status for the first half of 2013, highlighting key events, the impact of solar activity, and performance metrics. It details availability rates, particularly during geomagnetic storms, and describes the influence of solar events on ionospheric delay. Additionally, it outlines next steps for improving iono monitoring, including geographical expansions and planned updates to the system infrastructure. Users can access performance reports and support resources through the ESSP.
