A portable system for autonomous detection and classification of electromagnetic interference in the GPS band

The rapidly increasing use of wireless technology in critical systems has led to an increased vulnerability to radio interference. Radio interference is produced both naturally of all electronic systems but also through illegal jammers currently sold at low cost via the Internet. To continuously monitor the radio noise environment in critical systems are becoming increasingly important and in this paper an example of how low cost commercially available off-the-shelf equipment can be adapted to cost effectively implement a qualified detection and classification of radio noise environment at societal critical infrastructure.
