5 Base station operation
5.1 How to configure the AsteRx-U as an RTK
base station using the UHF radio
The AsteRx-U can itself also be configured to work as a base station and provide differential
correction data to one or more rover receivers.
Step 1: Setting the AsteRx-U base station position
Set the position as static
To work as a base station, the position of the AsteRx-U should be set to static. If not, the
AsteRx-U 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 ‘
GNSS
’
menu as shown in Figure 5-1.
Figure 5-1:
Setting the AsteRx-U base station position to static
Set the correct position
An accurate position of the antenna that is connected to the AsteRx-U 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. In the example shown in Figure 5-2, the position
stored under ‘Geodetic1’ is used. The stored 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.
