4.3.1 GPS data displayed
The virtual sky on the left represents the currently visible part of the sky above you,
with your position as the centre. The satellites are shown at their current positions.
The GPS receives data from the green and grey satellites but not from the red ones.
Signals from the grey satellites are only received, while green ones are used by the
GPS to calculate your current location. On the right you can see the satellite signal
strength bars (this feature is not available for PNDs with square display). Grey bars
are for the grey and black bars are for the green satellites. To identify satellites use
their numbers also shown in the virtual sky. The more satellites your GPS tracks (the
green ones), the better your calculated position will be.
