CHAPTER 3. CONF I GUR I NG THE ASTERX SB3
3.4 How to configure the AsteRx SB3 as a Base
station
This section describes the Base station con fi gurations applicable to the AsteRx SB3 .
I f the feature is included with the purchased product variant, the AsteRx SB3 can be set up
as a Base station receiver and provide di ff erential corrections data to one or more rover
receivers.
Step 1: Preparing the AsteRx SB3 as a Base station
Set the Base station position as static
To work as a Base station, the position of the AsteRx SB3 should be set to static. The Static
position mode can be selected in the GNSS tab as shown in Figure 3-17.
Figure 3-17: Setting the AsteRx SB3 Base station position to static
Set the correct position
An accurate position of the antenna that is connected to the AsteRx SB3 should also be set.
A Rover receiver in RTK mode calculates a position relative to the Base station receiver. The
default setting of
‘ auto ’ can be used for demonstrations however, for most other purposes
where an accurate absolute position is important, a properly surveyed position is advisable.
I n the example shown in Figure 3-18, the position stored under ‘ Geodetic1 ’ is used. The
static positions can be entered via the Advanced Settings menu on the same page. Pre-set
positions can be entered in either Geodetic or Cartesian coordinates as shown.
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.
