Abstract:	This paper investigates the simulation, Kalman Filter tracking, and Kalman Filter geolocation of a chirp{ type civilian Global Positioning System (GPS) jam- mer. The paper is divided into four parts. The rst two parts present information on the current genera- tion of GPS jammers and propose a simple method of jammer signal simulation. The third part outlines a method by which a Kalman Filter can track the state of the simulated signal at the output of a sim- ulated radio frequency (RF) front end. The method uses in-phase and quadrature accumulations, accu- mulation models, and noise models. The paper also considers the computational speed and numerical is- sues of the proposed system. Results are presented for the Kalman Filter signal tracker on data from a truth-model simulation. The fourth part outlines a particular implementation of a Time Dierence of Arrival (TDOA) jammer geolocation system and its associated state and measurements. A method of Time{of{Arrival measurement formulation which re- duces the required communication bandwidth between dierent TDOA stations is also presented. A jammer TDOA data collection campaign at White Sands Mis- sile Range in June of 2012 is detailed. Results of the proposed TDOA jammer geolocation system on two sets of real data are compared to Inertial Navigation
