Resumen:
The Galileo E6 band operates at a nonprimary frequency band within the L-band. This presents challenging situations in the vicinity of other, legitimate, radiolocation services. This is the case for Air Traffic Control (ATC) radar, which is seen as an in-band–pulsed interference by a GNSS receiver. This paper provides a detailed study of the impact of such interference, as well as localization approaches. Particularly, the paper describes the ATC jamming event captured on a GNSS permanent station, its effects on a real receiver, and how it was tracked to localize the source of interference. An ultra low-cost array-based solution is prototyped, based on commercial off-the-shelf devices, that implements a two-element array. Experimental results are shown and discussed using real data, validating the localization performance of the prototype. © 2019 Institute of Navigation
