Abstract
A positioning device includes a satellite positioning unit, an autonomous positioning unit and an error estimation unit. The satellite positioning unit acquires a position of a moving object determined by satellite navigation based on navigation signals. The autonomous positioning unit estimates a movement trajectory of the moving object based on satellite information, which is information before the position of the moving object is calculated in the satellite navigation and detection values of behavior detection sensors, and estimates the position of the moving object based on a reference point and the movement trajectory of the moving object.
