NMEA / DGPS
The Eagle View transmits data through the data port in the back of the
unit using NMEA 0183 format, version 1.5 or 2.0. This data is used by
other electronic devices such as marine autopilots for position and steer-
ing information.
DGPS on the other hand, is a data input. DGPS is an acronym for Differ-
ential Global Positioning System. Currently, it relies on a system of ground-
based transmitters that send correction signals to small DGPS receivers.
DGPS gives you more accurate positions than is otherwise possible.
The Eagle View can use the military grid
reference system (MGRS). It uses two
grid lettering schemes, which are re-
ferred to as standard and alternate
MGRS on the View. Your position and
datum in use determines which one to
use. In general, if the datum you’re us-
ing is valid for your present position, then
use the standard MGRS, otherwise use
the alternate MGRS.
Press the up or down arrow keys to high-
light the desired position format. Press
