Geomagnetic /dead reckoning integrated navigation method considering geomagnetic error
Dayuan Gao, Chao Wang, Hai Zhu · 2012
In geomagnetic navigation, the resulted position is not precise because of the influence of vehicle magnetic field. This paper used integrated navigation based on the geomagnetic measurement and dead reckoning. The geomagnetic error model is added to geomagnetic measurement model. The unscented Kalman filter is used to make two positioning method adjust each other. Simulation shows that the method is suitable for the integrated navigation of dead reckoning and geomagnetic measurement with error.
