Vehicle Integrated Navigation System

Ian Humphery and Christopher Reynolds

Abstract:	Fibersense Technology Corporation has developed an integrated navigation system for accurate navigation in urban environments. The first application of this system will be to improve the navigation accuracy of the New York City buses. The environment of New York City is particularly severe, and is probably the most challenging in the U.S.A. for GPS blockage and multi path. As part of the Americans with disabilities act the NYC buses must announce the location of the bus stop. The status of the buses is available at each bus stop (e.g. the next M2 bus will arrive in 6 minutes). During periods of good GPS data the system calibrates it sensors. This allows accurate navigation when the GPS data is unavailable or when the data is badly corrupted by multi-path signals. This also operates better in situations when a small number of satellites that are visible. This functionality can be added with very little additional cost compared with a system using only a GPS receiver.
