Positioning apparatus, positioning method, and storage medium for measuring position using both autonomous navigation and GPS
Abstract:
A positioning apparatus including: a first positioning unit which intermittently receives signals from satellites and carries out a first position measurement; a second positioning unit which carries out a second position measurement by adding information of a moving direction and a moving amount to positional information of a reference position; a positioning control unit which obtains positional information corresponding to positions along a movement path by the first position measurement and the second position measurement; a reference position updating unit which updates the positional information of the reference position based on a result of the first position measurement; a distance calculating unit which calculates a distance between two positions, i.e., between the reference position and a position obtained by the second position measurement; and a positioning timing control unit which controls timing to carry out the first position measurement based on the distance.
