Earthworks X300
Earthworks X300™ is a machine guidance grade control system that
brings the job into the cab. A digital terrain model (DTM) or digital site
design of the project is uploaded into an inside cab mounted touch screen
computer and displayed to the operator. Precision tilt sensors on the boom,
stick and bucket determine the position of the relevant attachment. The
inclusion of a GPS Compass device provides precise heading as well as
chassis pitch and roll. The inclusion of a GPS RTK rover (and base station,
if necessary) smart antenna completes full 3D machine position
capabilities. Full machine and attachment positioning is continuously
measured and displayed on the computer independent of tracking the
excavator with guidance of where to cut/fill relative to the DTM. This
ensures that the operator knows exactly what to do and where the machine
is on the job site.

Hemisphere GPS' A220™ (RTK Rover) delivers the precise GPS
positioning required for 3D.  The A220 can operate with an A221™(RTK
Base) GPS base station on site or through an RTK network.
