| Abstract: | Laser collimation mechanism, nonmagnetic two-dimensional rotating mechanism, two-dimensional rotating control and angle measuring mechanism were designed. Based on the principle of the automatic measurement for automatic geomagnetic dip angle and deflection angle, model machine was manufactured through the studying of magnetic fluxgate sensors configuration, data collection and general control device designing, and geomagnetic dip angle and deflection angle automatic algorithm. Through the experimental verification and error analysis of the principle prototype, the key technology of the geomagnetic absolute observation system is obtained. It provides technical support for the development of the automatic absolute observation system of geomagnetic field. The technology breaks through the limitation of artificial observation and provides a strong guarantee for the development of the observation model of geomagnetic unattended station. |
