| Abstract: | In this paper,a three-axis geomagnetic navigation sensor is designed to meet the needs of geomagnetic navigation in the multi information source integrated navigation system of bionic polarized light,geomagnetic and inertial navigation.The application and design requirements and implementation methods are introduced.The error analysis of the system is carried out,and the calibration measurement and compensation are carried out according to different error sources.The dynamic measurement of the three-axis attitude angle is realized,which provides an effective means to obtain the geomagnetic navigation information for the navigation system under the fusion of multiple information sources. |
