A long-distance journey requires the assistance of navigation The compass, one of the four great inventions, can show us the directions. Now we adopt advanced material science and electronic technology, in combination with geomagnetic field to realize geomagnetic positioning and navigation. As a new passive autonomous navigation method, geomagnetic positioning and navigation is different from radio navigation and satellite navigation and positioning technology, which is less affected by the environment and other factors. It is characterized by high invisibility, high precision, full independence, active positioning, all-weather and all-day coverage, and has broad application prospects and practical value in the fields of aviation, UAVs, ships, underwater robots, so that it has become the new hot spots and new direction for industrial development, and may replace the existing navigation technology in the future. In the fields of civil applications, the magnetic navigation product series developed based on GuoChuang Intelligent high-precision micro-magnetic basic sensor can not only provide high-quality heading and attitude data, but also realize high-precision magnetic field navigation within an area by high-precision magnetic field information and multi-sensor fusion algorithm, which has become another efficient means of positioning and navigation in addition to satellite navigation.

The key factors to determine the navigation precision include the precision of geomagnetic field description, magnetic field measurement technology and navigation algorithm. As a high-tech enterprise integrating research and production, over years, GuoChuang Intelligent has been committed to the research and development of sensors and related application products. Micro-magnetic basic sensor operates on the principle of the GMI effect and axial acquisition of magnetic sensitive materials. At the same time, the micro-magnetic basic sensor is used to keenly perceive and collect the data information of geomagnetic field, match with the geomagnetic map, and combine the navigation algorithm and the filtering algorithm, thus realizing geomagnetic positioning and navigation. Geomagnetic positioning and navigation applies not only to underwater, underground and high altitude navigation, but also to urban navigation.
