There are two icons on the left to show the status of the GPS connection and the
quality of reception.
4.3.2 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:
•
- Dark lamp means there is no communication on the selected port,
•
- Red lamp means connection to any GPS receiver has not been
established yet, so you need to set it up by using the Detect or Config.
Buttons,
•
- A slowly blinking yellow lamp means that there is no connection to the
GPS receiver, but The NVX235W Navigator is trying to connect,
•
- A fast blinking green lamp means that there is communication with the
GPS and data is being received.
4.3.3 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, The
NVX235W Navigator 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.
•
- Green means 3D reception. The GPS receiver has enough satellites to
calculate altitude. Position is generally correct (yet it can still be inaccurate due
to different environmental factors). The NVX235W Navigator is ready for
navigation.
