发明名称 Location Calculating Method and Location Calculating Device
摘要 A location calculating method includes acquiring measurement information by receiving satellite signals from positioning satellites and storing the acquired measurement information in a storage unit in association with acquisition time, calculating movement information that includes a movement direction and a movement distance by using a detection result of a sensor unit that at least includes an acceleration sensor and storing the calculated movement information in the storage unit in association with calculation time, and calculating a location at desired time by using at least the measurement information of which the acquisition time satisfies a predetermined proximity time condition and the movement information of which the calculation time is between the acquisition time of the measurement information and the given desired time.
