5.1. HOW TO CONFIGURE THE ASTERX-U MARINE FG AS AN RTK BASE STATION USING THE UHF
RADIO
Select the Datum of the antenna position
In the
Datum
fi
eld, you can select the datum to which the antenna coordinates refer.
The selected value is stored in the Datum
fi
eld of position-related SBF blocks (e.g.
PVTCartesian
) and also in any output differential corrections. Please note that the
Datum
setting does not apply any datum transformation to the antenna position coordinates.

Selecting the correction format and connection type
Output of differential corrections can be con

gured in the
Corrections Output
window as
Figure 5-3 shows. Click on
New RTCM3 output
to start the sequence of con
fi
guration steps.
The messages needed for RTK are selected by default.
RTCMv3 is the most compact and robust correction format. It is recommended to use this
format wherever possible.
