5.3  Monitoring RTK status 
Make sure the receiver is getting correction data by monitoring the RTK status in u-center (see Figure 
15): 
•  In the general information view (View > Docking Windows > Data), the RTK status is shown in the 
Fix status field as “Float” or “Fixed” if RTK is used. 
•  Alternatively, in the UBX-NAV-PVT message view, the RTK status is shown in the Carrier Range 
Status field as “Float” or “Fixed” if RTK is used.

Under open sky scenarios, if the receiver gets to a fixed state in less than two minutes, the receiver, 
antenna and correction service are compatible and working well.
