Abstract: An apparatus for correcting a golf address to be adhered to the body of a user, including: an input module in which the user pushes an input button to set a target azimuth while looking at a target point in a user setting mode; an azimuth calculation module comprising an accelerometer for measuring gravity direction, a gyroscope for measuring the x-axis, y-axis and z-axis directions of a golf club face, and a calculation processor for calculating the address azimuth of the user with respect to the target azimuth set in the input module by using the values measured at the accelerometer and the gyroscope when the user is in an address posture in a user execution mode; and an output module for outputting the address azimuth calculated at the azimuth calculation module.
