Start GPS Survey - Solve Localization

The Start GPS Survey Solve Localization screen is displayed when

you need a horizontal adjustment to solve your coordinate system. A

horizontal adjustment is required to solve your coordinate system any
time you begin a survey from an autonomous base position. This is

always the case when your projection mode is Ground – TDS
Localization

, since your first base setup is always from an autonomous

GPS position. This may be the case when your projection mode is
Mapping Plane

, when you set your first base on a new point. A vertical

adjustment is often desired, although not required before data

collection can begin.
The horizontal and vertical adjustments are
usually solved together. First, tap

Collect Control> to occupy some existing local

points as GPS Control points. Next, tap

Solve Localization … to open the Solve

Localization wizard to calculate the horizontal
and vertical adjustment parameters (Page

252).

After you successfully solve the localization

adjustment, the Start GPS Survey wizard will

close, and the GPS Data Collection screen will
open (Page 264). You are now ready to measure and store new points

in this job.
You can also choose to start the survey without solving the
localization, and complete the required adjustment later. Tap

Start Survey Now > to apply a temporary localization and begin data

collection. Any time during the survey, you can occupy the required

control points and solve the localization parameters. The GPS data

collected points will be updated to the proper local coordinate after
the localization is solved.
