MOBILE LOCATION POSITIONING DEVICE

摘要

PROBLEM TO BE SOLVED: To properly prevent fluctuation in mobile location information arising from vehicle stop conditions by properly performing vehicle stop determination. SOLUTION: A mobile location positioning device includes: a mobile location information deriving means for deriving mobile location information by using both satellite navigation and inertial navigation; a first mobile stop determination means for determining whether the mobile stops on the basis of an output value of an acceleration sensor and/or an angular velocity sensor; a second mobile stop determination means for determining whether the mobile stops on the basis of an output value or the like of a vehicle-mounted sensor capable of indicating a vehicle velocity; and a storage means for storing the mobile location information when the first mobile stop determination means determines that the mobile stops. When the second mobile stop determination means determines that the mobile stops after the first mobile stop determination means determines that the mobile stops, the mobile location information stored in the storage means is output as the current mobile location information.
