PROBLEM TO BE SOLVED: To provide a system and a method, in which association between test value data and orbital position data is performed further accurately and stably.SOLUTION: In synchronization with test value data, with an angular velocity sensor installed on a vehicle, angular velocity data representative of a yaw angular velocity are sequentially obtained so as to store them in time series together with the test value data; a time-series set of the angular velocity data satisfying a specified condition among stored angular velocity data is extracted; the time-series set is employed as a detection curve and matched with a curve in a curve alignment diagram of an orbit management diagram; a velocity is obtained from a yaw angular velocity as a representation of the detection curve and a curvature radius of the curve in the curve alignment diagram, having been matched with the detection curve; it is employed as a determined velocity in the detection curve; a velocity interpolating determined velocities is obtained as necessary; a distance is obtained by integrating these velocities; and by using the obtained distance, association between test value data in a processing section and orbital position data in the orbit management diagram is performed. |
