Mathematical underpinnings of crowdsource GPS jammer geolocation using signal strength readings from various locations

Abstract

Can we geolocate a GPS jammer using only smartphones located in the area? We present two mathematical approaches to solution and introduce a likelihood mapping. We validate these two approaches with a pedantic example, then contrast these two approaches by sensitivity analysis based on the example. Although our approach to solution is valid, we conclude from these experiments that real-world conditions inject too much error to make a direct mathematical solution of practical use. Future efforts center on real-world conditions and using a likelihood mapping.
