ESTIMATED POSITION CALCULATION DEVICE, ESTIMATED POSITION CALCULATION METHOD, ESTIMATED POSITION CALCULATION PROGRAM, AND RECORDING MEDIUM

摘要

An estimated position calculation device has a position calculation section (101) for calculating the current position of a mobile body by using satellite navigation; an acquisition section (102) for acquiring information on the environment in the periphery of the current position calculated by the position calculation section (101); a movement amount calculation section (103) for calculating the amount of movement of the mobile body based on movement information varying depending on movement of the mobile body; a determination section (104) for determining, based on the information acquired by the acquisition section (102), a correction parameter used for the calculation by the movement amount calculation section (103); and an estimated position calculation section (105) for calculating the estimated current position of the mobile body based on the movement amount calculated by the movement amount calculation section (103), the movement amount calculation being performed by using the correction parameter determined by the determination section (104), and based on the current position calculated by the position calculation section (101). By this construction, the amount of movement of the mobile body can be corrected depending on the environment in the periphery of the current position of the mobile body.
