If the active GRI Chain, secondary stations or offsets have been changed since
the waypoint was created, the waypoint will now reference the active GRI-chain
and secondary stations and adjust the TD coordinates accordingly. Remember that
the GPS is not relying on the LORAN signal for navigation and actually converts
the TD coordinate to a useful LAT/LON coordinate before storing the waypoint to
memory or using it for navigation. Because of this the unit can navigate to a TD
coordinate anywhere in the world.
