control points for closure. This routine will usually identify

the one or two bad points in a control point set, and then

prompt you to automatically remove these points as control
for the localization. If there is an ambiguous result for the

blunder detection, you will be prompted to collect extra check
points to provide the information needed to correctly identify

the blunders.

Localization Parameter Checking: Once the localization

solution is solved, hopefully with any potential blunders

identified and removed, Survey Pro will do one last

automated check for localization solution quality. The scale
factor of the solution is checked against a sensible tolerance,

and if it is too large or small, a message will show in the
results area.

In addition to the mechanisms Survey Pro uses automatically
to ensure a quality localization solution, you must also use

good common sense before using the final localization

solution. For a detailed discussion of how to ensure the
quality of the localization solution please see Page R-270 in

the standard GPS section.
