LORAN TD Setup
6. When finished, highlight the Save button, and press ENTER.
If the active GRI Chain, secondary stations, or offsets were changed
since the waypoint was created, the waypoint 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 secondary stations
to create a LORAN TD position. For more information, read our
LORAN TD Position Format Handbook, available at the Garmin
Web site at www.garmin.com/support/userManual.html.
