Abstract
Devices and methods are disclosed for determining position and controlling navigation by sensing movement through the Earth's magnetic field. Change in position is determined by integrating velocity which has been normalized for spatial and temporal field variation. Position is registered with respect to starting point and/or subsequently detected environmental feature. Signals are provided to actuator for guidance, navigation and control.
