Kathleen Kramer: Navigation: The Road to GPS and Getting Beyond It

December 3, 8:30 pm EST​

Navigation can be viewed as merely determining position or direction, but more commonly it relies on knowledge of position or direction to control or monitor movement from one place to another. Navigation techniques have evolved from ancient history to modern techniques based upon electronic navigation, including radio, radar, and satellite. GPS, and other constellation satellite systems in medium earth orbit, provide positioning information with global coverage. Finding and keeping track of just about anything have expanded applications far beyond military ones into civilian applications both for individuals and for large-scale commerce and transportation. As more and more vehicles and people rely upon it, threats to GPS navigation and implications from its vulnerabilities become of greater concern. Simple jamming of the GPS can render a system completely blind to its location, while more sophisticated attacks can spoof a GPS signal to control its navigation. Future trends and technologies to address the security issue and to move forward in navigation are discussed.
