  • When measuring with a GNSS receiver, the rover is usually connected to a base to receive RTK corrections.

  • The software offers the possibility to change the GNSS base coordinate. This operation is for example common after post-processing the raw data from the base and obtaining more accurate coordinates. The coordinates of all other points in the job are updated.


  • Open the Job tab.

  • Select Points/Measurements/Codes.

  • Open the Measurements tab.

  • Select Tools to open the list of available tools.

  • Select Edit and Shift GNSS base.

  • Base name: lists the base points available in the job. Select the base point for which you want to enter new coordinates.

  • Mode: select how enter the new base coordinates.

    • New coordinates LLH: insert new values for longitude, latitude and height.

      • Latitude: new value for latitude.

      • Longitude: new value for longitude.

      • Height: new value for height.

    • Shifting values LLH: insert values for shifting in longitude, latitude and height.

      • Δ Latitude: shift value for latitude.

      • Δ Longitude: shift value for longitude.

      • Δ Height: shift value for height.

    • New coordinates ENZ: insert new values for east, north and elevation.

      • E: new value for east.

      • N: new value for north.

      • Z: new value for elevation.

    • Shifting values ENZ: to insert values for shifting in east, north and elevation.

      • Δ E: shift value for east.

      • Δ N: shift value for north.

      • Δ Z: shift value for elevation.

Updating base coordinate updates all points measured from the base.
