5.

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.

6.

Collect a minimum of 2 control points to solve horizontal
localization. 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.

7.

When you have collected the minimum number of control points,
tap

3URMHFWLRQ to open the Projection screen.

8.

Tap

6ROYH /RFDOL]DWLRQ to open the Solve Localization wizard.

Note: If you are using localization for the vertical transform mode,
then the next screen will look like the illustration below. If you are
using ellipsoid heights, then the vertical column will be missing.

9.

In the list box, control points collected will be
identified with an

H

and/or

V

. Points marked

H

will

be used to solve horizontal localization. Points
marked with a

V

will be used to solve vertical

localization. You can select or deselect any point by
highlighting that point and then: tap the H and/or V
column beside that point; press H and/or V on the
keyboard.

Note: If your base was set up on a known point, that
point is an eligible control point. If your base was set up
on a new point, then it is not visible on the control point
list.

10.

If you wish to hold the scale of the GPS
measurements, but you want the localization adjustment to
correct for a rotation, check the

Solve Rotation Only

control in the

Fix H Scale to 1.0

box.

11.

Double check the selection of control points and tap

6ROYH !. The

localization parameters are computed using the selected control
points, and the next screen is opened with solution RMS values.
