Session Check

Before the residuals calculating for the Survey Sessions you need to have a number of sessions in the current job with corresponding data collected.

MAGNET Field calculates residuals for repeated measurements of the same physical point. The measurements should be performed in the same or different sessions. The physical point should be named identically in each session.

Note: You can save two and more points with the same name in the current job, if you select the Store as check point? radio button in the Point Check dialog. MAGNET Field performs the comparison with the last check measured and saved point of the selected session.

Note: You can see all check points for a point in the Check Points tab of the Edit Point dialog.

To perform the residuals calculation of Survey Sessions:

  1. Set the data needed for the task in the Input tab of the Session Check dialog. More...
  2. Select the computation type and calculate the task. More...
  3. Review the results of calculation. More...

Input Sessions

In the first Input tab, specify the calculation parameters:

  1. Select the Computation Type from the drop-down menu:
  2. MAGNET Field calculates residuals of repeated RTK measurements in geocentric coordinate system (X,Y,Z) regardless of the current coordinate system of the job. Depending on the selected computation type, MAGNET Field displays in report and saves residuals of repeated RTK measurements in the following coordinate systems:

  3. The tab contains the following columns:
  4. Select the check boxes near the desired sessions to include them into the calculation.
  5. Click the From Job button to open the Open Job dialog where you can select a job which contains a corresponding session for residuals calculation. When the job is opened, the desired session is displayed in the tab.
  6. Click Next.

Input Reference Data

In the second Input tab, specify the reference data for calculation:

  1. Set the Tolerances for the data used in the calculation. The content of the fields on this dialog depends on the selected computation type. You can use predefined types for tolerances from the drop-down list available after selecting the Use Predefined Types check box.
  2. Select the Reference Point from the map or the list for Closure, Duplicate Vector types of computations. More....
  3. Click the Calculate button.

Results

In the tab, review the results of the calculation:

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