First Claim
1. A terminal apparatus for positioning based on satellite signals from positioning satellites, comprising:
- satellite signal receiving means for receiving the satellite signals;
positioning position information generating means for generating positioning position information which indicates a position of the terminal apparatus based on the satellite signals;
moving vector information generating means for generating moving vector information which indicates moving vectors constituted by a moving direction and a moving distance of the terminal apparatus at predetermined time intervals by controlling movement history measuring means constituted by a rotational speed sensor, an acceleration sensor and a magnetic sensor;
estimated position information generating means for generating estimated position information which indicates an estimated position of the terminal apparatus at the current time based on the positioning position information and the moving vector information; and
estimated position information outputting means for outputting the estimated position information.
