Changing Parameters
If the default parameters are unacceptable, they may be changed by using either a PC
with communication software or a handheld computer with one of the Ashtech
interface programs. The GG Surveyor receiver works with most Ashtech interface
programs, such as Survey Control, GPS TOPO, and Mine Surveyor. Please see the
handheld software manual for more information.

Use the HI rod provided, to measure the antenna height.

Set the receiver power switch to ON.
During static surveys, you do not have to interact with the receivers. When
powered on, each receiver:
•
Performs a self-test
•
Searches and locks on all satellites "in view"
•
Makes GPS measurements and computes its position
•
Opens a file and collects all data into this file
The receiver uses default parameters for data collection, s no interaction with
the receiver is necessary to collect data. See "Default Parameters" on page
25 to check the default settings.
Set up a receiver over each mark for which you need to determine the
coordinates. Repeat these steps for all GG Surveyor receivers participating
in the survey.
During the survey, monitor the LED to ensure that the satellites are tracking.
After the survey, turn off the receiver. The receiver automatically closes the
file and saves the collected data.
