LORAN TD Setup
If the active GRI Chain, secondary stations, or offsets were changed
since the waypoint was created, the waypoint now references
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 latitude and longitude 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 and/or secondary stations
to create a LORAN TD location. For more information read our
LORAN TD Position Format Handbook, available at the Garmin
Web site, at
