Abstract :
The positioning performance of vehicular navigation systems based on a differential Global Position System (DGPS), dead-reckoning (DR), map matching (MM) and Kalman filter technologies are simulated. The vehicular navigation system using a 10-state extended Kalman filter to combine DGPS and DR can improve positioning accuracy. When DGPS signal obscuring occurs in the urban environment, DR with a map matching process can supplementally provide an accurate position for the vehicle. The simulation results of the paper can be used as a reference for the design, implementation and field tests of vehicular navigation systems
