摘要： The present invention provides a locating method, a drive test terminal and a hand-held terminal. Herein, the locating method comprises: a first terminal receiving an included angle value between a current advancing direction of a user and a due north direction, which is sent from a second terminal, wherein the first terminal is provided with a gyroscope, the second terminal is used to calculate the included angle value of the included angle between the current advancing direction and the due north direction according to the current advancing direction input by the user and a due north direction indication diagram, and send the included angle value to the first terminal; and the first terminal using the included angle value to correct an output angle of the gyroscope, so as to locate the first terminal. By the present invention, the directional angle may be accurately determined without using a magnetometer.
