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-168).

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-181).

Projection : opens the Projection screen (Page R-200).

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

project points can be examined.

Post Process : opens the Receiver Session screen (Page R-197), 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.

Control : opens the Occupy Control Point screen, where geodetic

coordinates are measured at a point with local coordinates and added

to that point record in the job file.
