AB - Current navigation systems provide position information using the satellite signals from the American GPS(Global Positioning System), and the GPS position accuracy is gradually improving by the developments of receiver algorithm and antenna performance. However, the accuracy is very limited in dense urban areas because the GNSS(Global Navigation Satellite System) signals are blocked, reflected, or diffracted by buildings. This paper describes the development and validation of GPASS(GNSS Position Accuracy Simulation System) that can simulate GNSS position accuracy for dense urban areas using 3-D building maps, signal propagation model, and the receiver correlator model. We carried out the feasibility tests for the area around the Tokyo Metropolitan Government Building famous for its skyscrapers. A good agreement was observed between our simulation results and the in-situ data: the difference of positioning rate was about 4.6%, and the difference of position accuracy was 3.0% approximately. The GPASS enables the evaluations of navigation serviceabilty on the spatial and temporal basis, which will be a useful reference for improving the service quality.
