POSITION CALCULATING METHOD AND POSITION CALCULATING DEVICE
First Claim
1. A position calculating method of calculating a position of a moving object using a first measurement result of a satellite positioning unit disposed in the moving object and a second measurement result of an inertial positioning unit disposed in the moving object, comprising:
- determining position calculation accuracy;
setting an influence level of the first measurement result on the second measurement result on the basis of the position calculation accuracy; and
calculating the position of the moving object by performing a coupling process of coupling the first measurement result and the second measurement result on the basis of the influence level.

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.
