Loran TD Setup Page
If the active GRI Chain, secondary stations, or offsets have been
changed since the waypoint was created, the waypoint now
references the active GRI-chain and secondary stations. You must
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 and 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 (www.garmin.com/support/userManual.jsp.)
