GNSS
In this area you will get detailed information about the GPS data, the easyTRX3 has to work
with.
GNSS Status
Here is shown an overview about course and speed over ground, the current position, satellites
available and in use as well as UTC world time.
Course over Ground:
Displays the current course over ground of the vessel.
Speed over Ground:
Displays the current speed over Ground of the vessel.
Latitude / Longitude:
Displays the current exact position of the vessel.
Satellites in view / Satellites in use:
Displays how many satellites are available for GPS positioning and how many are used for
GPS positioning in reality.
HDOP:
The horizontal dilution of precision display is a term used in satellite navigation and
geomatics engineering to specify the additional multiplicative effect of navigation
satellite geometry on positional measurement precision. The HDOP benchmark is 2.5. As
lower the value, as better it is.
Within the picture below you can see a HDOP value of 0.8 which is very good.
GPS Satellites
This is a display screen of satellites available (grey) and in use (blue).
