Detailed Procedure
Since the field procedure is the same for both horizontal and vertical
localization solutions, the instructions below cover both cases.
1. From the Control Points screen, select a
control point to occupy and enter the name
into the Point control. Horizontal control
points must have a valid northing and
easting coordinate in the local system.
Vertical control points may have a valid
horizontal coordinate (although it is not
used in the calculation) but must have a
valid elevation.
2. Level the rover antenna over the point and
tap Control Point to begin data collection.
3. When you are happy with the measurement, tap Accept.
4. Check the Results tab for details of the previous measurement.
Check the Map tab to see the number and position of control
points for this set up group.
5. Collect a minimum of one control points to solve horizontal
localization on a mapping plane. Collect a minimum of two control
points to solve a horizontal localization in an arbitrary ground
system with no projection and no datum. Collect a minimum of
three vertical control points to solve vertical localization. Collect
one vertical control point to solve just the localization vertical
shift when using a geoid model.
6. When you have collected the minimum number of control points,
tap Projection and Solve Localization to open the Solve
Localization wizard.
