Computation type: Check Cross Section

This computation type calculates residuals of two repeated measurements of distances between a central point of the X-section and any other point of the X-section. MAGNET Field calculates the distance measurements residuals in the horizontal and vertical planes.

MAGNET Field can perform comparison for:

There are the following requirements for the RTK measurements:

MAGNET Field calculates residuals for two selected sessions.

The application calculates the length residuals of two repeated lines in the geocentric coordinate system (X,Y,Z) and converts these values to a coordinate system that is based on the stereographic projection (N,E) with origin point in the location of the base station. More...

The calculation uses the following formulas:

dHD = HD1 - HD2;

dHt = Ht1-Ht2.

where:

To calculate the residuals, do the following steps:

  1. Select the check box for two sessions, which contain the measurements from the base station.
  2. Click the Next button to set tolerance values in the horizontal (dHD) and vertical (dHt) planes.
  3. Click the Calc button to start residuals calculation. The Results tab displays the residuals values.
  4. If the calculated differences in the horizontal and verticals planes are less than the threshold values, the test is passed and the icon is displayed.

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