PROBLEM TO BE SOLVED: To simplify signal connection to a navigation center controller by simplifying the operation processing of the navigation center controller and fully exhibiting the performance of a rotary sensor and a speed sensor. SOLUTION: A GPS 1 inputs differential information from a differential information reception part 6 via an operation-processing part 7 and a signal transmission/reception part 8 in addition to a satellite signal and outputs accurately absolute position information. The operation-processing part 7 inputs distance information from a wheel speed sensor 5 via the signal transmission/ reception part 8 and inputs angle information from a built-in optical fiber gyro 9 via the signal transmission/reception part 8, thus performing operation and hence obtaining relative position information. The operation-processing part 7 performs Karman filtering processing or the like to the relative position information for obtaining continuous position information, converts it to the same format as the data of the GPS 1, and outputs it to a navigation controller 2. |
