Start GPS Survey – Base Setup
The Base Setup wizard is used to setup an RTK base receiver, and to
configure the base reference position in Survey Pro.
Base Setup One – Pick Point
The first step of the Base Setup wizard is to pick a point
for the base reference position, and measure the antenna
height at the setup.
1. Set the base receiver antenna over the point.
2. Tap Setup HR to select your antenna type and
measure the slant or vertical height of the antenna.
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:
o
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.
o
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.
o
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.
