| Outline of Final Research Achievements |
In this research, methods that improve the accuracy and reliability of the satellite navigation system (GNSS) under severe circumstances such as urban and/or mountain areas. In such areas, signals from satellites are weaken and sometimes receivers can not detect them due to obstacles, trees, tunnels and so on.
In such circumstances, in this research, we developed navigation algorithms and methods that can keep the positioning accuracy by integrating the image information from the car-mounted camera, satellite positioning, inertial sensors.
