EVALUATION DEVICE FOR GPS MOVING PRECISION, AND COMPUTER SOFTWARE

摘要

PROBLEM TO BE SOLVED: To provide an evaluation device for GPS moving precision capable of evaluating the positional precision of a GPS receiver in moving, and speed dependency and acceleration dependency with respect to the positional precision of the GPS receiver. SOLUTION: This GPS moving precision evaluation device for evaluating the positional precision of the GPS receiver 121 in the moving is provided with GPS-mounted moving units 122, 123 for mounting a GPS antenna 124 for the GPS receiver to be moved, and a drive controller 119 for controlling a position and a speed of the GPS-mounted moving unit 123. The evaluation equipment is provided with a position detection precision analyzer 118 for comparing a value of positional information of the antenna 124 of the GPS receiver from the drive controller 119 with a value of positional information output from the GPS receiver121.
