Locating method, drive test terminal and hand-held terminal
First Claim
1. A locating method, comprising:
- 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, wherein the second terminal is provided with a due north direction indication diagram, and wherein 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 the due north direction indication diagram, and send the included angle value to the first terminal;
the first terminal setting a current angle of the gyroscope to 0 degree when receiving the included angle value; and
the first terminal using the included angle value to correct an output angle of the gyroscope, so as to locate the first terminal;
when outputting an angle, the first terminal using a sum of a current to-be-output angle of the gyroscope and the included angle value as a corrected output angle.
