7. 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.
8. 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.
9. Double check the selection of control points and tap Solve >. The
localization parameters are computed using the selected control
points, and the next screen is opened with solution RMS values.
10. For both horizontal and vertical, the solution type and RMS value
from the control points are displayed. The solution type will be
one of:
• Unique: the solution was calculated
using the minimum number of control
points or fewer. In this case, there is no
least squares solution to provide
residuals, so the numbers in the N Err,
E Err
, and/or V Err columns are
misclosures calculated from the control
points that are not used in the
solution.
• LSQ: the solution was calculated with
more than the minimum number of
control points. In this case, the least
squares solution can produce residuals, and the N Err, E Err,
and/or V Err columns show residuals for the points that are
used in the solution.
