Design and Implementation of a Mobile Phone Locator Using Software Defined Radio

Abstract

This thesis presents an approach for generating, detecting, and decoding a Global System for Mobile Communications (GSM) signal using software defined radio and commodity computer hardware. Using software designed by the GNU free software project as a base, standard GSM packets were transmitted and received over the air, and their arrival times detected. A method is provided to use software analysis of multiple receivers to locate an emitter based on the information received by the software radio. Results and accuracy analysis as well as limitations are shown based on initial testing. Complete implementation source code is provided in the appendices.
