GPS Security An Introduction

Global Positioning Security GPS focuses on vulnerabilities, real world threats, and mitigation protection strategies as GPS security is critical to modern economies, infrastructure, national defense, and personal systems as they rely on accurate positioning, navigation, and timing PNT provided by satellite systems like GPS. GPS is a part of a broader family of Global Navigation Satellite Systems GNSS which includes GLONASS Russia , Galileo EU , and BeiDou China . All of these systems transmit timing and positioning data from satellites to receivers on earth to determine location and time. Apart from navigation, GPS also provides timing signals that underlie financial transaction ordering, cell network synchronization, power grid stability, emergency response coordination, autonomous vehicles, and aviation and maritime navigation. The paper looks into the concept, pros, cons, and the usefulness of GPS Security to humanity. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.
