POSITION CALCULATING METHOD AND POSITION CALCULATING DEVICE
First Claim
1. A position calculating method comprising:
- performing a first operational process of calculating at least a position of a moving object using the measurement result of an inertial positioning unit disposed in the moving object;
performing a second operational process of calculating the position of the moving object using the result of the first operational process and the measurement result of a satellite positioning unit disposed in the moving object; and
adjusting an operational coefficient of the first operational process using the result of the first operational process and the result of the second operational process.

Abstract
To suggest a technique of more accurately calculating a position using both measurement results of a satellite positioning unit and an inertial positioning unit.
In a position calculating device (1), a first operational process of calculating at least a position of a moving object using the measurement result of an inertial positioning unit (2) disposed in the moving object is performed by a first operation processing unit (5). A second operational process of calculating the position of the moving object using the result of the first operational process and the measurement result of a satellite positioning unit (3) disposed in the moving object is performed by a second operation processing unit (7). An operational coefficient of the first operational process is adjusted using the result of the first operational process and the result of the second operational process by an operational coefficient adjusting unit (9).
