Claim:
1. An apparatus for correcting golf address set up comprising stance, posture and alignment, the apparatus being attached to a user's body, the apparatus comprising: an input module configured to receive a target azimuth set by a user setting mode, the target azimuth being set while facing a target point; in response to detection of a user takes an address posture, an azimuth calculation module comprising an accelerometer configured to measure a direction of gravity, a gyroscope configured to measure X-, Y- and Z-axis directions of a golf club face, and a calculation processor, using values measured by the accelerometer and the gyroscope, to calculate an address azimuth of the user with respect to the target azimuth set at the input module; and an output module configured to output the address azimuth calculated by the azimuth calculation module, wherein the user can adjust golf address set up using the output address azimuth, and wherein the calculation processor is further configured to calibrate the accelerometer and the gyroscope according to a plurality of target azimuth set by the user setting mode in order to increase accuracy of the accelerometer and the gyroscope.
