RTK

The following information will list two ways to connect to the local base station.

Option 1 - UHF Radio

RTK using Vasco Internal UHF Radio

The Vasco has an Internal Satel UHF Radio. This is a situation in which the local base station has a UHF Radio that is transmitting the RTK corrections. The radio setting in the Vasco must match that of the local base station.

Enter the following Options:

• RTK Port Type: Internal
• RTK Device: Internal Radio

  

• Base Station: Unless the base has a specific ID, leave the default box checked Use Any Base.
• RTK Radio Settings: Enter the following settings to connect to the Internal Radio of the Vasco GNSS Receiver.

  

  Grade will connect to the internal radio of the Vasco and retrieve the current settings. You will then change all radio settings to match that of the local base station.

• Set the parameters to match the settings being broadcasted by the site installed GNSS Base Station.

  

  • Protocol ____________
  • Channel Spacing ____________
  • Modulation ____________
  • Over Air Baud (If applicable)
  • Frequency ____________
  • Forward Error Correction ON or OFF

Go to Tools → Show Monitor Screen to check the quality of the RTK.

Note: RTK Fixed indicates that RTK has reached the highest quality and is receiving data.

If you don't get a Fixed solution, troubleshooting is necessary. Ensure all settings are correct.

• RTK Message Type: You can manually select and match the message type or select Auto.

  Note: Grade will automatically recognize the message type when this option is selected.
