Basic USMN Solution Process
The following describes the steps for a basic USMN solution process, without calculating uncertainty fields for the USMN composite group.
-
Ensure that the job file matches the requirements in Observations and Point Group Requirements for USMN.
-
From the Alignments tab, select Unified Spatial Metrology Network.
-
When prompted, select the instruments to include in the USMN network, then press Enter. The USMN dialog will be presented.
-
Ensure that the instrument settings are correct (moving/nonmoving, weights, DOF constraints, etc).
-
Click Best-Fit then Solve.
-
Examine the max error and ranking values.
-
If desired, click the Trim Outliers button and trim any measurements beyond your desired ranking.
-
Click the Solve button and observe the results.
-
Verify that Create composite group is checked.
-
Click the Apply button. The instruments/point groups will be located, and a USMN Composite point group will be created representing the ideal position of each measurement.
