Measurement of Magnetic Field Gradients

摘要

Technology for performing magnetic field gradient measurements is described. The magnetic field gradient measurements for specific positions on the Earth can be performed from a moving platform. The magnetic field gradient measurements can be identified as being affected by a level of error that exceeds a defined threshold. A correction value can be generated to compensate for the error in the magnetic field gradient measurements. The correction value can be applied to the magnetic field gradient measurements in order to obtain magnetic field gradient measurements with a reduced level of error.
