5 Base station operation
5.1 How to con fi gure the AsteRx-U3 as an RTK
base station using the UHF radio
The AsteRx-U3 can itself also be con fi gured to work as a base station and provide differential
correction data to one or more rover receivers.
Step 1: Setting the AsteRx-U3 base station position
Set the position as static
To work as a base station, the position of the AsteRx-U3 should be set to static. If not, the
AsteRx-U3 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.

Set the correct position
An accurate position of the antenna that is connected to the AsteRx-U3 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.
