Reference section 2 — Position coordinates
Using loran Reference Manual Revision D
Using loran
Many users have lists of fishing spots and
other waypoints that were recorded using
loran time differences (TDs). The
6000i lets
you continue using this invaluable data.
By interfacing your loran receiver to the
6000i , you can use the 6000i’s chart
plotting and advanced navigating features
with actual loran coordinates.
If you don’t have a loran receiver, you can
still use the Phantom Loran feature
described on page 49. With it, the
6000i
calculates “Phantom” loran coordinates
from GPS position information.
If you don’t plan to use loran, you can skip
these sections.
NOTE:
The loran you use must support the standard
NMEA 0183 “RMA” output data sentence struc-
ture. The Northstar 800 loran supports NMEA
0183 and is an ideal choice to use with the
6000i.
