Versatile and configurable GNSS interference detection and characterization station

In this paper, we present a versatile, configurable and customizable GNSS interference detection station. Up to three GNSS bands with a bandwidth of up to 80 MHz and a resolution of up to 8 bit can be continuously analyzed. If an interference is found, a user-customizable signal characterization is carried out to extract the interference signal’s parameters. The batch of affected data is archived for possible off-line analysis, including tagging of its appearance time and duration. Finally, the extracted characteristic is used to compare it with previously characterized ones for possible recognition. This information can then be used to gain insights about the interference source as well as providing the means for its removal. The architecture of the system, including the detection and characterization algorithms, as well as the web-based interface, is presented. The paper concludes with a presentation and discussion of the interferences found within a several weeks long measurement campaign near the motorway and airport in Nuremberg, Germany, in early 2017.
