Location of GPS Interference using Adaptive Antenna Technology

Kevin Bond and John Brading

Abstract:	An experimental antenna system is described which demonstrates the feasibility of detecting and locating the direction to the source of GPS interfering signals using a small number of antenna elements and largely existing adaptive antenna technology. The operating principles and measurements of the performance under controlled conditions are described. The measured accuracy of the system is +/- 5 degrees in azimuth. The sources of error within the experimental system, potential improvements and projected performance limits are discussed. Flight trials have been carried out by NATS (National Air Traffic Services, UK), using the system to survey potential interfering sources within the UK. The general conclusions of flight trials are included.
