Ph.D. Forum Abstract: Accurate and Robust Low-Cost GNSS Localization

While the use of the Global Positioning System provides a natural choice for sensor network localization, the high-accuracy requirements of certain applications prevent the use of low-cost GPS hardware as part of their localization solution. Low cost GPS hardware provides poor accuracy when used in isolation, but the sharing of measurement data between a network of common GPS receivers provides an opportunity to mitigate errors and provide a sub-meter localization solution. The goal of this work is to develop such a system by creating robust techniques that are resilient to outliers and other error sources encountered in the real-world.
