Operating Modes

OPERATING MODES
The GEONAV can operate in two different modes, Cursor and
Navigation, each giving access to different functions.
CURSOR MODE
When the GEONAV is in Cursor mode, the crosshair cursor is
displayed. The CURSOR key allow browsing through the elec-
tronic chart, as well as editing or creating the route. See the
R o u t e Section for more details.
To enter the Cursor mode, press the CURSOR key.

NAVIGATION MODE

In Navigation mode, the boat's position icon replaces the
crosshair cursor and several data windows can be accessed.
To enter the Navigation mode, press the PAGE key repeatedly.
As the fix is valid, the windows sequence is the following:
SATELLITE > NAVIGATION > MENU > DEPTH SOUNDER > TRIP >
LAT/LON > INFO > RUNWAY
The Depth Sounder window is displayed provided that data
is received from a depth sounder.
The Info window is displayed provided that a NAVIONICS
cartridge featuring Tides and Currents data is active (see the
I n f o W i n d o w Section).

SATELLITE WINDOW
NOTE: If a NAVIONICS cartridge with the Tides and Currents feature has been
inserted, the Satellite window will disappear as soon as a valid fix is obtained and be
replaced by the Info window.
At start-up the satellite window
displays how many and which
satellites are tracked by the GPS
receiver.
The outer circle represents the
horizon, the inner one identifies
a 45° elevation with respect to
the horizon, and the central
circle points to the zenith.
The small squares with numbers
show the satellites available. The
numbers of differential satellites,
if any, are displayed from bot-
tom to top.
As soon as the satellite is tracked by the GPS receiver, the
square turns red. The bars displayed on the left identify the
signal quality; the longer the bar, the higher the signal qual-
ity.
On the left of each bar, two digits indicate numerically the
signal / noise ratio.
Additional information:
•
Day, month, year, local or Greenwich time (at the first
start-up the GEONAV is initialized to Greenwich Time).
•
Boat's position (lat / lon) (or the latest valid fix if the GPS
receiver is still searching for satellites).
•
Data on the current satellite situation (number and fix).
