| Abstract: | In order to achieve the rough north seeking in large azimuth, the motion characteristics of pendulous gyroscopes in both non tracking state and tracking state in large azimuth are analyzed respectively. Then based on the motion characteristics of gyroscopes, two rough north seeking methods are put forward and analyzed in non tracking state and tracking state. Finally, the experiment on the rough north seeking method in tracking state is carried out. The results demonstrate the feasibility of the method and the reasons of low precision are analyzed. The necessity of designing high precision servos system is presented on basis of the results. |
