Trimble Puts GPS to Work on Construction Motor Graders

SUNNYVALE, Calif., Mar. 15, 2000 -- Following the successful launch of its Global Positioning System (GPS) machine guidance system for bulldozers, Trimble (NASDAQ:TRMB) introduced today the SiteVisionTM GPS system for motor graders.
 
The system is designed to help construction equipment operators increase productivity and work in a stakeless environment, saving time and money. It puts the site design in the cab where operators can actually see the site plan. Using precise GPS technology, the system allows machine operators to accurately perform earthmoving operations for highway and road construction, residential and commercial sub-division projects as well as other land development.
 
"The construction equipment market is one of the most exciting new platforms for GPS machine guidance," said Mark Nichols, Trimble's senior director of mining, construction and agriculture. "We have already proven that SiteVision GPS can enable bulldozer operators to increase productivity by dramatically cutting construction times on large scale earthmoving projects. These same benefits can now be realized on the motor grader."
 
Trimble's SiteVision machine guidance system has already been utilized by bulldozer operators around the world for a wide range of earthmoving projects, including golf course development, airport expansions, land reformation, railway and road construction, housing developments and shopping malls.
 
The SiteVision GPS system for motor graders provides operators with real-time graphical information for on-grade and on-line guidance. The system provides full 3-dimensional (3D) positional information for earthmoving in a stakeless environment, achieving horizontal and vertical accuracies better than 3cm (one-tenth of a foot).
 
The system includes a 36-channel, dual antenna GPS receiver, two GPS antennas on masts, a wireless data radio, an on-board color display and three lightbars for guidance.
 
Trimble's SiteVision GPS system for graders is anticipated to be available in May 2000. The system will be distributed through Trimble's worldwide dealer network.
