Loran TD System
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 U.S. Coastal Conﬂ uence 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 transition from using LORAN
to using GPS. The GPSMAP unit automatically converts GPS coordinates to
LORAN TDs for those who have a collection of LORAN ﬁ xes for favorite ﬁ shing
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 meters. When the unit is placed in the LORAN TD format
mode, it simulates the operation of a LORAN receiver. Position coordinates may
be displayed as TDs, and all navigation functions may be used 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 Setup TD ﬁ eld
before storing the waypoint. After the waypoint is stored in unit memory, it
will always reference the LORAN chain number and secondary stations currently
selected in the Setup TD ﬁ eld. If you enter a different LORAN chain number,
change the secondary stations or offsets in the Setup TD ﬁ eld, the active waypoint
information will reﬂ ect those changes. Since the GPSMAP 76 does not rely on
the LORAN signal for navigation, it can reference a different GRI chain and/or
secondary stations and still navigate to the location stored in memory.

The Location Format ﬁ eld is located under the Setup—Location tab in the
Main Menu. The ‘LORAN TD Setup’ window contains the ﬁ elds to select the
Loran GRI-Chain Number, Primary and Secondary Stations, and TD Offsets.To setup Loran TD from the Main Menu:1. Using the ROCKER, highlight the “Location Format” ﬁ eld on the ‘Location
Tab” and press ENTER.
2. Highlight ‘Loran TD’, press ENTER. This will display the LORAN TD Setup
3. To change the settings of any of the ﬁ ve ﬁ elds, highlight the ﬁ eld, press
ENTER, select/enter the desired setting then press ENTER.
4. When done, press the PAGE Key to return to the Main Menu.If the active GRI Chain, Secondary Stations or Offsets are changed, all
waypoints stored in the units memory will update and reference the the new
settings when displayed as a LORAN TD. It is important to note that the saved
coordinates of the waypoint are not being modiﬁ ed, they are only being displayed
in reference to the different GRI Chain, Secondary Stations or Offsets. Remember
that the GPS is not relying on the LORAN signal for navigation. The GPSMAP 76
converts the TD coordinate to a LAT/LON coordinate before storing a waypoint
to memory. Because of this the unit can navigate to a converted TD coordinate
anywhere in the world.
