Abstract
A method, system and inertial navigation unit are provided in order to facilitate location determination by calibrating a location determined by an inertial navigation unit. The method may receive a magnetic pulse, such as a magnetic pulse generated by a lightening strike, with a plurality of first magnetometers and with a second magnetometer co-located with the inertial navigation unit. The method may also compare a representation of the magnetic pulse received by the plurality of first magnetometers to a respective representation of the magnetic pulse received by the second magnetometer. Further, the method may correct the location determined by the inertial navigation unit as a result of the comparing of the representation of the magnetic pulse received by the plurality of first magnetometers to the respective representation of the magnetic pulse received by the second magnetometer.
