AVLN 2000 automatic vehicle location and navigation system

This prototype system is being tested at the University. The positioning component consists of a GPS Trimble TANS (Trimble Advanced Navigation System) receiver, a pair of Nu-Metrics odometers, and a map-matching module, all integrated by a seven-parameter state vector Kalman filter to yield continuous positioning of the vehicle. An on-board GRiDCase EXP microcomputer is used for real-time computations and display. The system is being field-tested in a route network in the northwest quadrant of the City of Calgary. Enhanced area master files from Statistics Canada are used to produce the road network database.<
