1.9.7 Rover: Configuration procedure overview
This overview describes how to set the rover configuration by using the UBX-CFG-VALSET
message view that is available in u-center 18.05 or newer. The UBX-CFG-VALSET message
view needs to be set up for the configuration group and configuration keys that you wish to
set. Once a configuration key is selected, you need to add it to the list by clicking the 'Add to
List' button. Once it is in the 'Configuration changes to send' table you can edit or read the
current receiver value. If you click on the Key item in the list, it will then be highlighted and
allow you to set the value or read the current set value.
To configure the module for rover operation the following procedure needs to be carried out:
• Set the UART1 interface for the correct host baud rate.
• Select Group: CFG-UART1, Key name: CFG-UART1-BAUDRATE. Please see Figure 13 .
• Add it to the list and highlight it. It will now give you the option of setting the value or
reading the current value. Please see Figure 14 .
• Now add the value, e.g. 230400 baud, into the new Value window that appears below
the list. Please see Figure 15 .
• Now set the configuration by clicking the Send button at the bottom of the message
tree view. Remember to then set u-center baud rate to match the value you set in the
receiver.
• We need to enable some UBX messages to view the status of the rover. Select Group CFG-
MSGOUT, Key name: CFG-MSGOUT-UBX and select the UART1 required messages. Add each
message to the list and then set the value of each to 1. Then click Send. Please see
Figure 16 .
• Please ensure all the required RTCM3 messages, most importantly RTCM 1005, are being
received regularly by viewing the messages in the UBX-RXM-RTCM view in uCenter. Please
see
Figure 17
• Once the rover has started to receive valid RTCM3 messages, it will transition from 3D Fix to
3D/DGNSS to Float and to Fixed mode. This will only occur if it is receiving all required RTCM
messages, including RTCM 1005, and the signal conditions are sufficient. Please see
Figure
18
• Note that the receiver by default will attempt a RTK Fix solution, however it can be configured
to use an RTK Float only solution by setting the CFG-NAVHPG-DGNSS configuration item.
