The objective of this activity is to monitor the different GNSS signals, extending the current capabilities of the MONITOR network, and to exploit the database to provide relevant input for the evolution of EGNOS V3 (updated models and reference scenarios, statistics and specifications, worst-case estimates, representative data samples, ...). Thus, the objective can be broken up into two main parts:
1. Monitoring and analysis of Evil Wave Forms (EWF) also known as a non-nominal signal distortions.
2. Monitoring, analysis, and characterization (including development of technical specifications) of environmental effects due to ionosphere.
