4.1 How to configure the PolaRx5S as an RTK
base station
The PolaRx5S can be con fi gured to work as a base station and provide di ff erential correction
data to one or more rover receivers. The steps below describe how to con fi gure the position
of the reference station and output di ff erential corrections over an Ethernet connection.
Connecting to the PolaRx5S over Ethernet is described in Section 3.3.3.
Step 1: Configuring the PolaRx5S base station position
Set the position as static
To work as a base station, the position of the PolaRx5S should be set to static. I f not, the
PolaRx5S will still work as a base station however the position of the rover may show more
variation. The
‘ Static ’ position mode can be selected in the ‘ Position ’ window of the ‘ Station ’
menu as shown in Figure 4-1.

Set the correct position
An accurate position of the antenna that is connected to the PolaRx5S should also be set. The
default setting of
‘ auto ’ can be used for demonstrations however, for most other purposes,
a properly surveyed position is advisable. I n the example shown in Figure 4-2, the position
stored under ‘ Geodetic1 ’ is used. The antenna position can be entered in either Geodetic or
Cartesian coordinates.
Select the Datum of the antenna position
I n 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 di ff erential corrections. Please note that the Datum
setting does not apply any datum transformation to the antenna position coordinates.
