WAAS is a GPS navigation system with differential correction by means of
geostationary satellites. The US FAA has been testing this system and expects more
field tests in 2003. Similar systems, using Satellite-Based Augmentation Systems
(SBAS), are under development in Japan (MSAS: MSAT Satellite-based
Augmentation System) and Europe (EGNOS: European Geostationary Navigation
Overlay System). They are said to be fully interoperable and compatible. MSAS and

EGNOS are expected to become fully operational in 2004 or after.
As the WAAS utilizes the same frequency as the GPS, a single antenna can receive GPS and WAAS signals. Currently
two Inmarsat GEO satellites are available for receiving the WAAS signal: AOR-W and POR. Major contributors of an
error in a single frequency GPS system are receiver clock drift and signal delays by refraction. The WAAS reference
stations on the earth monitor the GPS constellation and route GPS error data to the satellites via the master earth
station. The Inmarsat or communication satellite broadcasts the differential corrections to marine and aviation users.

Four chart orientations are available in the course plot display:
True Motion North-up, Relative Motion North-up, Course-up and
and Auto Course-up modes. In the True Motion modes,
coastlines remain stationary on the screen while your vessel
moves according to its actual speed and course. In the Relative
Motion mode, your vessel is kept at the screen center and
coastlines move relative to your vessel.
The course plot display shows your vessel's position with a
motion trend vector, route, position, speed and course. Your

vessel's heading and speed are
indicated by a vector at your
present position. Display colors
can be changed for optimum
visibility depending on ambient
light conditions.

Important navigational
information can be clearly read
from a distance.

Helps you keep your vessel on
its intended course.

Useful for following legs along
your planned route.

The GP-1850W series are GPS/DGPS/WAAS plotters
with video plotting and echo sounding capability
designed for pleasure craft and coastal fishing boats.
This compact and cost-effective series offers extremely
accurate position fixes - 10 m for the basic GPS, 3 m
where WAAS service is available and 5 m with DGPS
(DGPS version).

The Display modes include Course Plot, Nav Data,
Steering and Highway. The Steering mode provides an
intuitive indication of course to steer and cross-track­error. The Highway mode is useful when you are
following a series of waypoints along a planned route.

The GP-1850WF and GP-1850WDF with the 50/200
kHz echo sounder module present detailed information
on fish and bottom. The echo sounder data can be
displayed jointly with course plot or alone on the full
size screen.

The useable chart cards are Furuno MiniChart/
Navionics

®

Nav-Chartor C-MAPNT Chart cards.
Chart cards contain accurate spot sounding, coastlines,
depth contours, buoys, lighthouses and other
navigational features.

Incorporating a powerful 50/200 kHz, 600 W echo

sounder module, the GP-1850WF/1850WDF present
an echogram in addition to the course plot display.
Full-screen echo sounding modes include Normal
(single- or dual-freq), Bottom-lock, Bottom Zoom,
Marker Zoom and A-scope. Selection of sounding
range, phasing, gain, display mode, frequency and
other settings are simple with the softkeys at the
right of the screen. A water temperature graph can
be displayed if an appropriate temperature sensor
is provided.

In the Auto Course­up mode, automatic
resetting takes
place at a course
change of 22.5° and
the vessel's
intended course is
kept at the screen
top like a head-up
display.
