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.
You must know your GRI chain number, secondary stations to create a LORAN TD position. For
more information please read our LORAN TD Position Format Handbook, available at the GARMIN
web site, at www.garmin.com/support/userManual.html.
