4.1.11. Summary and conclusions 
The main advantage of Demonstrator 2 with respect to Demonstrators 1 is the availabilty of a real- 
time visualisation through the web-based graphical user interface (GUI) of information allowing to 
characterise current interference situation. The NMEA logs produced by the demonstrator were not 
optimised for a deep analysis of individual interference events and estimating the characteristics of 
interfering signals in post-processing. These logs, however, still are very helpful for assessing long- 
time behaviour of the interference situation. So, with the help of the information containing in 
these logs the following conclusions can be drawn for the executed measurement campaign:
