Abstract
Disclosed are exemplary computer-implemented methods and systems for geophysical field sensing based navigation. One example of a computer-implemented method includes: receiving geophysical field data from at least one geophysical field sensor; synchronizing timing of the geophysical field data; de-noising, using a de-noising machine learning model, the geophysical field data removing noise from local sources of noise for the at least one geophysical field sensor to produce de-noised geophysical field data, the de-noising machine learning model trained using ground truth map data and training data corresponding to the ground truth map data; receiving map data from a geophysical map engine; performing error estimation by comparing the de-noised geophysical field data with the map data; and updating a position estimation based at least in part on the error estimation.
