http://rtk.local/

The Base Configuration menu.

The base station's location can be provided with two methods, which affect the absolute-accuracy of its RTK corrections:

• Fixed: Users can provide a fixed position for the base station's location in [ECEF] or [geodetic] coordinates. This is used to provide RTK corrections to rovers, for the most accurate surveying results in relation to fixed coordinates on the planet Earth.
  • For example, surveying property lines, locating or installing utilities, or other applications where the accuracy of measured positions must be repeatable.
• Survey-In: The base station configures its location, based on an average of measurements made over a specified time frame. This is used to provide RTK corrections where the absolute-accuracy of a rover's position isn't necessary and relative-accuracy of its measurements are sufficient.
  • For example, aerial surveys, mapping trails and campsites, or drafting construction plans where the accuracy of measurements in relation to one another (i.e. relative-accuracy) is important. However, the location of those positions, in relation the planet Earth (i.e. absolute-accuracy) is irrelevant.
  info

  Any errors in the base station's location, are propagated directly into the rover through the RTK corrections. Therefore, if the base station is off by 2m in a specific direction; all the RTK measurements from a rover, using that base station, will also be off by 2m in the exact same direction.

After the desired settings have been changed, scroll to the bottom of the configuration webpage and click the Save Configuration button. Once the Success : All Saved message appears, reload the webpage to update the configuration settings.
