Reference station and rover pairing 

This section is provided for users with two C099 boards and provides configuration information when 
setting up a C099-F9P as a reference station to provide local RTCM corrections for a C099 rover.  This 
connection uses Wi-Fi connectivity to maximize range for untethered operation. 

6.1

 

Wi-Fi connection between two C099-F9P boards 

This set-up relies on establishing a peer-to-peer Wi-Fi connection between two C099 boards for short 
base-line applications, e.g. drones and the like. 

Separate ODIN-W2 configuration files are required to enable the reference station and rover C099 
boards to operate as an Access Point and client respectively. 

Prior to use, the reference station C099-F9P needs RTCM3 output messages enabled and its position 
surveyed-in. When  the  device  is  surveyed-in it will  enable  output  of the RTCM3 1005 message to 
enable the rover to begin RTK operation.  Consult the Integration manual [4] for information relating 
to reference station operation for more information. 

In this example the C099 reference station sends corrections to a C099 rover and the rover transmits 
NMEA and UBX messages back to the base. The rover operation can be viewed remotely with u-center 
connected to the reference station’s ODIN-W2 COM port. 
 

     

                                                                                             

 

          
 

Figure 28: Reference and rover C099-F9P set up. 

  

The sub-sections below describe the steps required to configure the boards for Wi-Fi operation plus 
the settings needed for rover and base operation. 

 

 

Configuring a C099-F9P rover for Wi-Fi operation 

The following steps provide guidance on configuring the C099 ODIN-W2 Wi-Fi for rover operation: 

 

Disconnect any UART multiplexor jumper connections before proceeding. 
 

 

Connect the rover unit via USB to a PC.  

 

Install the u-blox s-center evaluation application. 

 

Open s-center which will show the following view:
