The RTK dialog

The RTK dialog with an optimal connection.

Once the viDoc RTK rover is successfully connected to PIX4Dcatch, the RTK dialog will be visible. This screen displays information that can be used to monitor the status of the connection and the resulting accuracies.

•    The header contains the RTK connection icon, access to the RTK device, and Bluetooth settings dialogs.
  •  The green RTK icon indicates the successful connection to the viDoc RTK rover.
  •  The RTK device settings icon displays the current settings input for the RTK connection. 
  • The Bluetooth settings icon displays the current Bluetooth device selected.
•    Indicates the battery level for the viDoc RTK rover. It would be advised to charge before each use.
•    RTK dialog horizontal and vertical accuracy level. Indicates the accuracy to which the viDoc RTK rover is expected to achieve.
•    NTRIP RTK Status. Indicates the status of the RTK NTRIP connection.
  • RTK Fixed: Accuracy in the range of a few centimeters(in).
  • RTK Float: Accuracy in the range of 1m(3ft)
  • DGNSS Only: Accuracy in the range of up to 10m(32ft)
  • Autonomous GNSS fix: Accuracy in the range of more than 10m(32ft)
  • No Fix: The data is not valid, there are not enough satellites visible, or there are internet connection problems.
•  HDOP(Horizontal Dilution of Precision) Indicates the current quality of the position and distribution of the satellites. Generally, the HDOP value is considered ideal below 1.
