Title: A Mathematical Solution to GPS Interference

Abstract: You know that annoying guy in the commercial who continually asks, “Can you hear me now?” Part of the motivation for that ad is the interference that typically occurs when phone signals reflected from nearby objects combine with the direct signal and degrade its quality. My talk will focus on some research I’ve done for the military to eliminate the effect of these reflected signals when the signals are from GPS sources (which are very similar to those used in cell phone signals). This problem is important to unmanned urban navigation, landing jets on aircraft carriers, testing the stability of large structures (like dams), geophysical monitoring for earthquakes, and rescue operations. Its solution involves a number of different areas of mathematics (such as calculus, dynamical systems, probability, statistics, and numerical analysis) which I’ll introduce and explain in the context of this problem.
This talks supposes only knowledge of basic calculus and should be accessible to most math/physics/engineering undergraduates.
