Select an existing job file point, and check the boxes to set 

if you want to 

Use This GPS Control Point For:

 horizontal, 

vertical, or horizontal and vertical control. 

3.

 

Level the pole over the point and tap  

Start Control Point Occupy…

 to begin an occupation on the 

selected point and open up the Occupy Control screen. 

4.

 

When you are satisfied with the GPS observation, tap 

Accept

 to create the GPS control point and go back to the 

Localization Status page. 

5.

 

If you have enough control, the wizard will advance to the 

Localization Check page.  If you do not yet have enough 
control, repeat steps 1 to 4 until the wizard advances to 

the next page. 

6.

 

If you wish to proceed directly to data collection without 

collecting the control required to solve the localization, 
you can tap 

Start Now

.  A temporary localization will be 

applied so you can start data collection. 

Note: You must establish the control to solve the localization 
at some point in order to calculate the proper local 

coordinates of your base and any points you measured while 

the temporary localization was in place.  This step can be 
completed in the field, or later in the office if desired. 

Localization Check (Collect Check Point) 

The Localization Check page shows you the base point name 

and the name of the points used for the GPS Backsight or 

GPS Resection.  The display will prompt you to collect an 
additional GPS control point to check the setup. 
7.

 

When you are ready to start a GPS control point collection 
for your check, tap 

Occupy Check >

 to open the Select 

Check Point screen. 

8.

 

Select an existing job file point, and check the boxes to set 

if you want to 

Use This GPS Control Point For:

 horizontal, 

vertical, or horizontal and vertical control.
