you select:
• An existing point with geodetic coordinates, the GPS base
receiver is set with this coordinate, and the base reference
position is configured in Survey Pro.
• An existing point with plane only (N,E,Elev) coordinates
when the coordinate system is solved, the plane
coordinate is transformed into geodetic, the GPS base
receiver is set with this coordinate, and the base reference
position is configured in Survey Pro.
• A new point, or, an existing plane point when no
projection is solved, you 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 position 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.

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.
