Abstract
Example computer-implemented methods and systems for estimating geophysical fields for magnetic navigation. One example computer-implemented method includes storing, at a navigation object, an offline baseline estimation model. Online geophysical field model data not stored on the navigation object are received at various times at the navigation object. Control logic is used to select at least one of (1) the offline baseline estimation model and (2) the online geophysical field model data to use to estimate geophysical fields for the navigation object at a variety of specified times.
