Research of a Navigation and Localization System Based on Geomagnetic Measure
Aiming at shortages of accumulated drifting errors in inertial navigation, a new method of navigation has been researched deeply. The technologies of geomagnetic measure used in the system of navigation are researched and analyzed deeply in this article. A high precision model of geomagnetic data which is adapted to the system of geomagnetic navigation in an area is put forward. Additionally, three ways of optimizing arithmetic that searching the most similar data are put forward, which not only reduce the time of matching operation but also accelerate the speed of the response in the system of navigation. At last, an experiment of simulation is conducted in a computer and can emend the drifting errors in inertial navigation effectively.
