PROBLEM TO BE SOLVED: To make it possible to seamlessly navigate in a route in which an outdoor route and an indoor route coexist in consideration of calibration of an independent navigation sensor.SOLUTION: Regarding guidance of an outdoor route, a route guide processing unit 172 performs route guide using positioning results of a GPS unit 160. Regarding guidance of an indoor route, the route guide processing unit 172 performs route guide using the sensor output of an independent navigation sensor unit 140 when calibration of the independent navigation sensor unit 140 started at a predetermined time is completed. Regarding the guidance of an indoor route, the route guide processing unit 172 performs route guide using the sensor output of a vibration sensor unit 150 when calibration of the independent navigation sensor unit 140 started at a predetermined time is not completed.SELECTED DRAWING: Figure 1 |
