Development of a deployable low cost interference detection and localization system for the GNSS L1/E1 band | CU Experts

Overview

There have already been a number of well documented cases where the GNSS signals have been interfered by different sources. A number of different methods has been developed to counteract this. One problem with doing experiments to validate the accuracy of interference detection system is that the GPS L1 band is protected, therefore it is difficult to get permission to deliberately broadcast on those frequencies. In this paper we present a novel way to test such a system. The proposed method will be validated by deploying a number of low cost nodes and then an attempt to localize the interference will be made.
