When the north angle is greater than 400, a certain gyro theodolite of The PLA 1001 Factory can not normally find the North. In this paper, the author deduces a mathematical formula between pendulum gyro in the tracking state speed and the north angle, a coarse north seeking method based on tracking speed detection method is proposed. Analysis and experimental results show that this method can achieve omni-directional north seeking at any initial erecting azimuth within 2 minutes, accuracy can meet the requirements of coarse north finding, shortened the time and improve the fitting accuracy, solve the problem of north seeking large azimuth.
