RTK survey data links

Real‑time kinematic surveys can use a data link to send observations or corrections from the base station to the rover. The rover then calculates its position in real time.

To check the status of the data link during an RTK survey, tap the Real-time correction icon in the status bar or the GNSS functions screen. You can also configure the data link from the Data link status screen.

To obtain RTK data by:

• Radio connected to the controller and communicating with the radio at the base station, use a radio data link. See RTK radio data link.
• Cellular phone or modem connected to an Internet server using an IP address, use an Internet data link. See RTK Internet data link.
• Cellular phone or modem dialing the cellular phone or modem at the base receiver, use a dial-in data link. See RTK dial-in data link.
