"Constellation Map" screen
NOTE: This screen is only active when the installed GPS receiver is capable of receiving National Marine Electronics
Association (NMEA) sentences of the GSV (satellites in view) type. These include the AFS 162, AFS 252, AFS 262,
and AFS 372 receivers and Trimble® equivalents.
Press the "GPS2" icon on the navigation bar to display the
"Constellation Map" screen.
The screen is divided into an upper table area and a lower
map area. Both areas provide valuable information on the
number of satellites that are currently visible and tracked
(in use) by the GPS receiver.
The table area displays information about a maximum of
10 satellites. Each satellite is identified by its number. The
number is black when the satellite is tracked (in use) and
red when the satellite is only visible (not in use).
NOTE: A satellite can be visible, but not tracked, because
its signal is too poor.
For each tracked satellite, the table provides its Signal-
to-Noise Ratio (SNR), elevation, and azimuth. For each
visible satellite, the table provides only its elevation and
azimuth; the SNR value is grayed out.
The map area below the chart visually represents the lo-
cations of the satellites in relation to the vehicle and true
north. All visible and tracked satellites are shown and
identified by their number in the same black and red color
code.
NOTE: The vehicle location is always at the very center
of the map.
