A system and method for determining errors and calibrating to correct errors associated with field sensors, including bias, scale, and orthogonality, includes receiving and providing to a processor angular rate data and a first field vector relative to a first reference directional field and a second field vector relative to a second reference field from at least one field sensor. The processor is configured to relate the first field vector and the second field vector to the angular rate data to determine an error of the at least one field sensor. The processor is also configured to identify a compensation for the error of the at lease one field sensor needed to correct the first field vector and the second field vector and repeat the preceding to identify changes in the error over time and compensate for the changes in the error over time.
