Abstract
A positioning apparatus includes: a satellite positioning device calculating a satellite positioning coordinate based on a navigation signal received by a navigation signal receiver; a movement quantity calculator acquiring a signal from an inertial sensor and sequentially calculating a movement quantity of the movable object by inertial navigation from receiving a navigation signal until receiving the signal from the inertial sensor; a virtual reference point determinator sequentially determining a virtual reference point after receiving the navigation signal; and a position determinator determining the position of the movable object sequentially based on the movement quantity of the movable object from the virtual reference point. The virtual reference point determinator determines that the virtual reference point is obtained by multiplying respective weighting factors on the position of the movable object and the satellite positioning coordinate, and increases the weighting factor used to multiply the satellite positioning coordinate.
