DATA COLLECTION AND REPRODUCTION SYSTEM AND PROGRAM OF DATA COLLECTION AND REPRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To heighten accuracy in test results. SOLUTION: This data collection and reproduction system comprises: a GPS information generation processing means for generating GPS information on the basis of GPS satellite radio waves received when a vehicle is traveling; a data collection processing means for collecting the GPS information and travel data when the vehicle is traveling; a radio wave generation processing means for generating GPS satellite radio waves for test on the basis of the GPS information; and a data reproduction processing means for relating travel data to the GPS satellite radio waves generated by the radio wave generation processing means and reproducing the travel data. Since the GPS satellite radio waves for test are generated on the basis of the GPS information, and the travel data is related to the GPS satellite radio waves for test and reproduced, it is possible to heighten accuracy in test results when overall communication performance and a navigation system are tested.
