SATELLITE 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.
As soon as a satellite is tracked by the GPS receiver, the number inside
the square is displayed in reverse. The bars displayed on the left identify
the signal quality; the longer the bar, the higher the signal quality.
On the left of each bar two digits indicate numerically the signal quality
relevant to that satellite.
A value greater than 40 indicates a good signal quality.
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 is still search-
ing for satellites).
• Data on current satellite situation (number and fix).
• SOG, COG and altitude.
The latitude and longitude values relevant to the boat's position are dis-
played as soon as three satellites are tracked and a 2D fix (two dimen-
sions) is available.
The altitude value is available only if four satellites are tracked and a 3D
fix is obtained. As soon as a valid fix is available, the GEONAV will auto-
matically switch to Navigation mode and display the boat's position at
the best chart range available; the window at the bottom of the screen
will indicate the boat's course, speed and chart range.

Since the GPS receiver is initialized in Italy, the time to get the first fix
Plus
Elite
will depend on the areas you want to navigate in; within the Mediterra-
Regatta
nean Sea the GEONAV should get the first fix in less than 12 minutes,
whereas in other parts of the world it can take up to 30 minutes.
Once the unit gets the first fix, the time for the following fixes is a few
minutes.
If the boat is in an area covered by a differential station, when the built-
Elite
Regatta
in antenna is used together with a DGPS, the top of the screen will
display the "FIX 3D-DIFF" or "FIX 2D-DIFF" message.
