A single base station provides data for any number of GPS equipped machines

Machine control using GPS alone, controls the blade using elevations derived from RTL GPS. It works where the line of sight is difficult to achieve.

With GPS update rates ( 10 Hz) GradeStar provides accuracies better than 30mm ( 0.10ft ) Works anywhere on the jobsite within 10 km ( 6.25 Miles ) from the base station and even further with repeaters.

Better accuracy is achieved with a combination of laser control and GPS. The GPS system provides the horizontal positional data and the laser system provides the vertical data.

GPS significantly reduces the need for grade stakes, while providing automatic control of the machines cutting edge.

Three Dimensional Machine Control means less time spent on re-staking or remarking a site.

The Digital Terrain Model (DTM) of the site is displayed on the highly visible touch screen monitor in the cab. This gives the operator plain view , cross-section view and cut/fill information.

Transitional and vertically curved grades are constructed easily and seamlessly.

Adjustments to the blade of the machines are made in real time.

The systems modular components are easily transferred from on piece of equipment to another.

Laser Alignments Computer System using GradeStar can collect and map over 200 acres in a single day.

GradeStar can collect points manually or automatically

On the move, at speeds up to 20 mph, the system can automatically capture points while driving across the site.

Data is filtered and checked by the program and shown on the screen as it is logged into the system.

GradeStar collects the points and provides a topo view while still at the jobsite.

A manual capture mode allows the operator to name each point individually.

With GradeStar only one person is needed to set up the system and run it.

The versatility of the GradeStar system allows it to interface with many different survey instruments.
