4.1. HOW TO CONFIGURE THE ASTERX-U3 FOR RTK
Step 2: Con fi gure the UHF radio
To con fi gure the AsteRx-U3 to receive differential correction data from a remote base station,
the internal UHF radio should fi rst be powered on as shown in Figure 4-2.
To con fi gure the remaining settings, you will need to know the following four parameters
from the base station transmitter:
• bandwidth (sometimes referred to as channel spacing) of the transmitter
• frequency of the transmitted signal
• protocol of the transmitted data
• error correction method (FEC) of the transmitted data

After changing the settings click on OK to fi nalize the settings. Each time the con fi guration
is changed, a pop-up in the lower right-hand corner will prompt you to save the new
con
fi guration as the boot con fi guration. Clicking on ‘ Save ’ will cause the AsteRx-U3 to boot
with the new con fi guration after a power cycle.
The frequency and bandwidth are con fi gured via the Advanced Settings menu. Note that,
the baud rate of the connection depends on the Protocol and Bandwidth settings as given
in Appendix 9.2.
