<p>According to an aspect of the invention, there is disclosed a moving body position detection system comprising:
a dead reckoning navigation information acquisition unit (13) that acquires dead reckoning navigation information including a direction (¸1) of a moving body:
a position identification unit (13) that identifies a position (61) of the moving body;
a position prediction unit (13) that predicts a predicted position (62) at which the moving body is to arrive after an elapse of a predetermined interval from the position (61);
a direction angle calculation unit (13) that calculates a difference direction angle that is a difference between a direction (¸2) from the position (61) of the moving body to the predicted position (62) and the direction (¸1) of the moving body ;
a direction angle correction unit (13) that corrects the difference direction angle if the difference direction angle is equal to or larger than a threshold; and
a position update unit (13) that updates the position (61) of the moving body based on the difference direction angle.</p> |
