I know that the satellites broadcast the ephemeris tables (the precise orbital information of the satellite) every 5 minutes or so but what about the calculation of magnetic declination? It's a pretty complex model. ... OK. That pretty well establishes that the table is stored in the firmware. I'm curious as to how detailed...

Values from 1955 through 1967.5 were derived using the source data of Table 4 of the "Coast and Geodetic Survey Publication 40-2, United States Magnetic Tables for 1960.0". ... Declination values for 1970 are from the U.S. polynomial model which produced map I-911, Magnetic Declination in the United States Epoch 1975.

Furthermore, the deviation changes with the ship's heading, resulting in a deviation table as shown below. The vertical axis states the correction in degrees West or East, where East is ... Secular variation: The change of magnetic declination in time with respect to both strength and direction of its magnetic field.

Every five years, the International researchers who produce the IGRF table data for magnetic declination calculations update their data. This will allow very accurate calculations for the previous 5 years since their last data update, as well as very accurate extrapolation for the next five years.
