Satellite Window - Geonav 7C Manuel D'emploi Et D'installation

Satellite Window

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 qual-
ity; the longer the bar, the higher
the signal quality.
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).
•
SOG, COG and altitude.
The latitude and longitude values relevant to the boat's posi-
tion are displayed as soon as three satellites are tracked and a
English

2D fix (two dimensions) 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 automati-
cally switch to Navigation mode and display the boat's posi-
tion at the best chart range available; the window at the bot-
tom of the screen will indicate the boat's course and speed.
To recall the Satellite window, press the EXIT key repeatedly
until it appears.
