Abstract:
A positioning apparatus includes: a first measuring section to directly measuring its own present position; a second measuring section to measure an azimuth and a movement of a user; a movement method judging section to judge a movement method of the user based on the measurement result by the second measuring section; an azimuth specifying section to specify a movement azimuth of the user based on the measurement result by the second measuring section; a movement speed calculating section to calculate an average movement speed in a period where the movement method of the user is judged to be a movement state by car; and a position calculating section to obtain a movement position by integrating a movement distance into the specified movement azimuth at the average movement speed to reference position information obtained by the first measuring section when the user is in the movement state by car.
