The invention discloses a multidirectional GPS antenna for eccentricity measurement and a use method thereof, the multidirectional GPS antenna for eccentricity measurement comprises a positioning base, a compass fixing seat is fixedly arranged in the center of the top of the positioning base, and a magnetic pole pointer is arranged in the compass fixing seat. Two symmetrical semi-arc-shaped fixing plates are fixedly arranged on one side of the top of the compass fixing seat, rotating holes are formed in the two semi-arc-shaped fixing plates along the circle center positions of the arc surfaces, rotating rods are movably connected to the inner walls of the two rotating holes, and deviation rods are movably connected to the outer walls of the rotating rods. According to the invention, the values of H2, X and Y are eliminated through the actually measured values of the GPS machine head, namely, the actual offset and elevation influence quantity of the GPS machine head are eliminated, so that the measured data ar
