Field-test Results from an Autonomous Electromagnetic Interference Detector in the L1 Band

Patrik Eliardsson, Björn Gabrielsson

Abstract:	The availability of low cost GPS jammers through the Internet is a potential risk for the society, if these devices are used nearby safety critical systems. This risk has created a demand of detecting these devices so that proper function of safety critical timing and positioning systems can be guaranteed. Therefore it has become increasingly important to continuously monitor the electromagnetic environment, for instance close to safety critical infrastructure. In this paper an electromagnetic interference detection system with signal classification capability is described. Results from field tests are presented were commercial GPS jammers have been used as stimuli for the detection system. We show that the implemented classification method also serves as an early warning of emerging GPS performance degradation.
