Navionics 5 GPS Receiver User Manual


 
26
Latitude and longitude relevant to the boat’s position are
displayed as soon as three satellites are tracked and a 2D fix
is available.
The altitude value is available only if four satellites are tracked
and a 3D fix is performed. As soon as a valid fix is available,
the GEONAV will automatically 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
and speed as well as the chart range.
Since the GPS receiver is initialized in Italy, the time to get the
first fix will depend on the areas you want to navigate; within
the Mediterranean Sea the GEONAV is supposed to get the first
fix in less than 12 minutes, in other areas 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.
