or Data Collection Control

The Control Points screen is used to measure GPS control points to
use in the localization adjustment, or to check the location of exiting

points against GPS measurements and the latest coordinate system.
GPS Status: displays the current solution
type, radio signal quality, number of satellites

used, and the receiver’s estimate of the

horizontal precision of the current point. If this
area is tapped, the GPS Status screen will

open (Page R-176).

Set HR : displays the current antenna

measurement and measure to setting. You can

change the antenna measurement by entering
a new value in the edit box. This new antenna

height will be sent to the receiver with your

next control or check point collection. You can
change both the antenna measurement and measure to setting by
tapping on Set HR to open the Receiver Antenna screen (Page R-188).

Projection : opens the Projection screen (Page R-208).

View Points : opens the View Coordinates File screen, where the

project points can be examined.

Post Process : opens the Receiver Session screen (Page R-204), where

you can occupy a point for a post processing only session. This allows
you log a session in the post processing file using an existing point

name without changing that point record in the job file.

Check : opens the Check Control Point screen, where the local

coordinate computed from the measurement is compared to the local

coordinate’s known value.
