Loran Td Setup; Loran Td Feature; Using The Loran Td Format - Garmin 76CS Plus Owner's Manual

LORAN TD Setup

LORAN C is a radio navigation aid operated and
maintained in the United States by the United States
Coast Guard. The name LORAN is an acronym for
"LOng RAnge Navigation." The LORAN system
covers the entire United States and the United States
Coastal Confluence Zone. From the perspective of
a mariner, the system is used for ocean and coastal
navigation. It can be used as a supplemental system
for harbor and harbor approach navigation, and it is
used for inland navigation by recreational vehicles.

LORAN TD Feature

The LORAN TD (Time Delay) feature eases the tran-
sition from using LORAN to using GPS. The unit au-
tomatically converts GPS coordinates to LORAN TDs
for those who have a collection of LORAN fixes for
favorite fishing spots and other waypoints recorded as
TDs. You can display your position as a TD or enter
waypoints as TDs. The accuracy to be expected from
this conversion is approximately thirty (30) meters.
When the unit is placed in the LORAN TD format
mode, it simulates the operation of a LORAN receiv-

er. You can display position coordinates as TDs and
use all navigation functions as if the unit was actually
receiving LORAN signals.

Using the LORAN TD Format

When creating new waypoints using LORAN TD
coordinates, you must set the correct LORAN chain
number and secondary stations in the Chain Number
field before storing the waypoint. After the waypoint
is stored in unit memory, it will always reference the
LORAN chain number and secondary stations cur-
rently selected. If you enter a different LORAN chain
number or change the secondary stations or offsets,
the active waypoint information will reflect those
changes. Since the 76CS Plus does not rely on the
LORAN signal for navigation, it can reference a dif-
ferent GRI chain and/or secondary stations and still
navigate to the location stored in memory.
Open the Location Setup page and select Loran TD
for the Position Format. You must know your GRI
chain number and secondary stations to create a LO-
RAN TD position.
