摘要

A measuring unit obtains measurement data of an object measured on the basis of a signal from a GPS satellite and angular velocity of an object output from an angular velocity sensor. An offset value computing unit estimates a running condition of the object on the basis of the measurement data and the angular velocity. The offset value computing unit sequentially derives temporary offset values while changing combination of the measurement data and the angular velocity in accordance with the estimated running condition of the object and, after that, executes statistical process on the temporary offset values, thereby deriving an offset value. An angular velocity conversion coefficient computing unit sequentially derives temporary angular velocity conversion coefficients on the basis of the measurement data and the angular velocity and, after that, executes statistical process on the temporary angular velocity conversion coefficients, thereby deriving an angular velocity conversion coefficient. An angular velocity converting unit derives final angular velocity on the basis of the angular velocity conversion coefficient, the offset value, and the angular velocity.
