Note: If this receiver has already set an antenna with Survey Pro,
the measurement and settings will be recalled from the registry, so
you will not have to do this step again.
3. Enter a name for the Base Point . You can select an existing point
from the job or you can enter a new point name for the job. If you
select:
• An existing point with geodetic coordinates, we send these
reference coordinates to the GPS receiver and configure the
base coordinate in Survey Pro.
• An existing point with plane only (N,E,Elev) coordinates, we
calculate geodetic coordinates from the current projection,
then send this reference position to the GPS receiver and
configure the base coordinate in Survey Pro.
• A new point, or, an existing plane point when no projection is
solved, we start from an autonomous position. You will GET
an autonomous position from the GPS receiver for your first
base setup. You then SET this reference position in the GPS
receiver and configure the base coordinate in Survey Pro.
Note: It is strongly recommended that you use only one autonomous
GPS base position in a job. If you must use multiple autonomous
setups in a single job, you will be prompted to setup and select a
separate site record for each setup group.

Set the Base
The final step of the Base Setup wizard will depend on the base point
chosen. If the base (lat, lng, ht) is known or can be computed, the
final step is to SET the base at the known geodetic position. If the
base (lat, lng, ht) is not known, the final step is to GET an
autonomous position to SET the base with.
