PURPOSE: A device for measuring GNSS(Global Navigation Satellite System) data accuracy is provided to calculate a real true value for three-way movement according to time by performing three-way uniform velocity circular movement with a GNSS antenna. CONSTITUTION: A GNSS data accuracy measuring device is composed of a housing(110), a rotary frame(120), a GNSS antenna(130), a cable(140), a GNSS receiver(150) and a driving motor(160). A space is formed in the housing. A rotation hole(111) is formed on the upper side of the housing. The rotary frame is exposed to the outside and passes through the rotation hole from the inside of the housing. The cable is connected to the GNSS antenna through a hollow. The GNSS receiver is connected to the cable. The driving motor rotates the rotary frame.
