GPS receivers are heavily used in aviation for both visual and instrument flights. There is a need for a backup system so that enroute and non-precision approaches can be flown without reliance on ground based systems should GPS be unavailable. We propose to use barometric pressure, airspeed, low-cost inertial sensors, three-axis magnetometer along with high-fidelity geomagnetic models, and an ...

More than 6,000,000 auto accidents occur in the U.S. each year, with about one third resulting in injury and 40,000 resulting in fatality. Approximately thirteen percent of these crashes involve pedestrians. A much broader group of generalized roadway obstacles including pedestrians, other automobiles and non-fixed objects, is responsible for over ninety percent of the accidents. A reasonably p ...

Cities must perform detailed assessments of sidewalks and streets, including curb ramps, pedestrian signals, crosswalks, street furniture, and other components to determine compliance with the Public Rights-of-Way Accessibility Guidelines. However, current assessment methods are inadequate or unreasonable due to time and resources required. The objectives of this project are to: 1) develop elect ...

Positioning and navigation have become a mainstay of everyday life in the U.S.; applications of interest include navigation of vehicles of all kinds, infrastructure mapping, and safety of life systems. Many of these recent applications have become possible through the GPS. With the recognized vulnerabilities of GPS, it is evident that equivalent backup systems must be developed. One possible so ...
