Research Interests & Projects

Location information adds value to a number of systems and services.  Although global navigation satellite systems such as GPS perform well in many circumstances, there are environments and situations in which other technologies may hold an advantage.  Current research focuses on the use of optical, ultrawideband, and WiFi signals and sensors for indoor positioning and navigation.  Investigation of methods for integrating various indoor positioning technologies is also underway. A parallel field of investigation is vehicle to vehicle ranging systems.
