Abstract
A moving body position detection system including an unit acquiring dead reckoning navigation information including a moving body direction; a unit identifying a moving body position based on the dead reckoning navigation information on the moving body; a unit predicting a predicted arrived position of the moving body after a predetermined interval from the position of the moving body based on the dead reckoning navigation information on the moving body; a unit calculating a difference direction angle between a direction from the position of the moving body to the predicted position and the direction of the moving body; a unit correcting the difference direction angle if it is equal to or larger than a threshold; and a unit updating the moving body position based on the difference direction angle.
