1. A method for controlling navigation of a platform comprising:
- providing a sensing element for producing a tangential velocity of a charge during translational movement of sensing element, detecting, utilizing the sensing element, compound velocity signals induced in the sensing element from a combination of the tangential velocity and a translational velocity of the charge caused by the translational movement of the sensing element, utilizing a processor connected to the sensor, processing the detected signals to determine a velocity signal, integrating the velocity signal to determine a change in position signal, and utilizing a controller coupled to or implemented by the processor, registering the change in position to an initial position or to a detected environmental feature of known location for determining a navigation signal.

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.
