Solve Localization – Control Points
6XUYH\ 3URMHFWLRQ +RUL]RQWDO 6ROYH /RFDOL]DWLRQ« 
The Solve Localization screen is used to pick control points for a least
squares localization solution, or to key in parameters for a manual
localization solution.
A list of all occupied control points matching the current
base set up group is displayed. If a point is to be used in
the horizontal and/or vertical transformation solution, a
Yes will appear in the H and/or V column for that point.
If it is not to be used in the solution, that field will be
blank.
Each point can be selected for horizontal or vertical
control by tapping the corresponding column or pressing
the [H], or [V] key on the keypad. You can double tap on
a point to display information about that point.
6HOHFW + : selects the currently highlighted point for
horizontal control in the least squares solution.
6HOHFW 9 : selects the currently highlighted point for
vertical control in the least squares solution.
6HOHFW $OO : selects all of the control points to be used in the least
squares solution.
&OHDU $OO : un-selects all of the control points.
Fix scale to 1.0 : Check the Solve Rotation Only control to constrain
the least squares solution to a scale of 1.0. Do this when you want to
orient your GPS to an existing grid but you want to hold the scale of
the GPS measurements.
Solution | Solve H : Check Solve H to use the selected control points in
a least squares solution or to use the horizontal values from the
manual entry card.
Solution | Solve V : Check Solve V to use the selected control points in
a least squares solution or to use the horizontal values from the
manual entry card.
0DQXDO (QWU\! : opens the screens used to manually enter a set of
localization parameters for a horizontal and/or vertical solution.
