GNSS Interference Detection and Localization using a Network of Low Cost Front-End Modules

Jonas Lindstrom, Dennis M. Akos, Oscar Isoz and Marcus Junered

Abstract:	This paper discusses the set-up of a network of low cost ASIC front-end modules for detection of interference and localization of interference sources in GNSS L1/E1 band. Such a system has been designed to not only provide an IF-data stream but also gain control level samples. These two information channels combined provide the ability of detection and localization of both weak and strong signals. Presented herein are the theory and mathematics used along with validation from tests where the position of the interference source is known.
