PROBLEM TO BE SOLVED: To provide a current location calculation device capable of calculating a correct current location of a vehicle. SOLUTION: The device is configured to calculate a horizontal direction circulating angular acceleration azc of the vehicle 10 by compensating an output of a gyroscope sensor 11a, whenever fulfilling with a condition in which the vehicle is circulating by a predetermined angle and the condition in which GPS signal can not be received by a GPS sensor 11c. Thereby, the position and the direction (travelling direction) of the vehicle can be calculated accurately, because the output value of the detected signal of the gyroscope sensor 11a can be compensated when the vehicle approaches into parking lot which has spiral slopes.
