Abstract
In a position calculating device of a moving object including a satellite positioning unit and an inertial positioning unit, a position calculation accuracy determining unit determines a position calculation accuracy and sets an influence level of measurement result 1 of the satellite positioning unit on measurement result 2 of the inertial positioning unit on the basis of the determined position calculation accuracy. The position of the moving object is calculated by performing a coupling process of coupling measurement result 1 and measurement result 2 on the basis of the set influence level.
