Computation type: Check Two Coordinates

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

The calculation uses the following formulas:

dHD = HD1 - HD2;

where:

To calculate the horizontal distance 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 plane (dHD).
  4. Click the Calc button to start residuals calculation. The Results tab displays the residuals values.
  5. If the calculated difference is less than the threshold values, the test is passed and the icon is displayed.

    If the calculated difference is more than the threshold value, 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. Semicolons in the file name will be automatically replaced with the underscore symbols ("_").

    Note: When performing export to a GNSS-Pro (*.DLF) file, original raw data and session check calculation results will be included to the output files. The observation method will be automatically specified as "Indirect" in the output files (this flag is required by the "GNSS-Pro"application).
