4.2.1 GPS data displayed
The virtual sky on the left represents the currently visible part of the sky above you,
with your position as the center. The satellites are shown at their current positions.
The GPS receives data from both the green and gray satellites. Signals from the
gray 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. Dark
bars are for the gray and orange 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.
Additional pieces of information on this screen are: current position in
latitude/longitude format, elevation, speed, date, time and calculated accuracy.
Note: Accuracy can be affected by several factors the GPS cannot take into account.
Use this accuracy information only as estimation.
There are two icons on the left to show the status of the GPS connection and the
quality of reception.
4.2.2 GPS connection indicator
In the middle to the left there is a lamp similar to the ones used for switches. This
one has more colors and represents more values:
•
a fast blinking green lamp means that there is communication with the GPS
and data is being received,
•
other colors may not appear with a built-in GPS. Should any of
these appear, this means a faulty operation of your device.
4.2.3 GPS data quality indicator
In the top left corner there is a satellite dish to show the quality of the GPS position.
Different colors represent different signal quality:
•
black with a red cross means there is no connection with the GPS device.
•
red means the GPS is connected but no GPS position is available,
•
yellow means 2D reception. A GPS position has been acquired, AVIC-S2 is
ready for navigation, but the GPS is using enough satellites for calculating the
horizontal position only. Elevation data is not provided, and the position error may
be significant.
