Computation type: Check Control Points

This computation type calculates residuals of horizontal and vertical distances between two pairs of the following points:

MAGNET Field can perform comparison for:

There are the following requirements for calculation of the residuals:

MAGNET Field calculates residuals for one selected session and control points of the current job.

The application calculates the residuals of distance measurements in horizontal and vertical planes between control points and measured RTK points in geocentric coordinate system (X,Y,Z) and converts the values to a coordinate system that is based on stereographic projection (N,E) with origin point in the location of the base station.

The calculation uses the following formulas:

dHD = HD1 - HD2;

dHt = Ht1 - Ht2:

where:

To calculate the residuals, do the following steps:

  1. Make sure that your job contains control point(s).
  2. Select the check box for session, which contains the measurements from the base station.
  3. Click the Next button to set tolerance values in the horizontal (dHD) and vertical planes (dHt).
  4. Click the Calc button to start residuals calculation. The Results tab displays the residuals values.
  5. 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.
