GEOMAGNETIC FIELD DISTURBANCE MONITORING AND CORRECTION

Systems, methods, and devices for performing geomagnetic field distribution monitoring and correction. One system includes a reference magnetic sensor configured to detect components of a magnetic field at a first location and generate reference sensor signals, non-transitory computer-readable storage media storing instructions, and at least one electronic processor. The at least one electronic processor is configured to execute the instructions to receive the reference sensor signals from the reference magnetic sensor, compute a local adjustment factor based on the reference sensor signals, receive operational sensor signals from an operational magnetic sensor configured to detect components of the magnetic field at a second location, compute an orientation representation based on the operational sensor signals, and apply the local adjustment factor to the orientation representation to generate a corrected orientation representation.
