Computation type: Closure

This computation type performs loop closures calculation for the RTK GNSS observations that form a closed loop. MAGNET Field can perform comparison for:

There are the following requirements for the RTK measurements:

MAGNET Field calculates residuals for two selected sessions only.

The application calculates loop closures in the geocentric coordinate system (X,Y,Z) and converts these values to a Cartesian topocentric coordinate system (N,E,H). More...

If the number of common points in the both sessions is even, then the loop closing order is the following:

If the number of common points in the both sessions is odd, then the loop closing order is the same as for even number of points except for the final loop:

To perform the closure calculation, do the following steps:

  1. Select the check box for two sessions which contain the measurements from different base stations. Click the Next button:
  2. The application analyzes the closure figure(s) and displays the tab,
  3. where:

  4. Click the Next button to set tolerance values for each axis and select the origin point from the map or the list . More...
  5. Click the Calc button to start residuals calculation. The Results tab displays the residuals values.
  6. If the calculated differences for all axes are less than the threshold values, the test is passed and the icon is displayed.

    If the calculated differences for any axis is more than the threshold values, the test is not passed and the icon is displayed.

    Click the button to save the calculation results to *.txt or GNSS-Pro (*.DLF) file format.
