SUNNYVALE, Calif., June 3, 2009 — Trimble (NASDAQ:TRMB) today introduced version 11.1 of its Trimble® GCS900 Grade Control System. Building on the version 11 announced in February at Trimble Dimensions 2009, version 11.1 further expands the mix of machines supported and provides enhanced wireless data transfer capabilities between the construction office and the machine operator in the cab. Further expansion of machine mix and support for on-machine data transfer demonstrates Trimble's continued commitment to meet the contractor's needs for productivity technology across all phases of the construction life cycle.

New Machine Configurations

The Trimble GCS900 v11.1 release includes new 3D configurations for soil compactors, broadening the range of machine types supported. Heavy highway contractors can utilize key Trimble machine control components on more machines and for more applications, allowing both new and existing users to realize a higher and more rapid return on their investment in technology.

These new configurations for soil compactors allow contractors to implement total station-based machine control technology across more machines in their fleet. The Trimble SPS Series Universal Total Station is ideal for either high accuracy work or operating in areas with limited or no GPS coverage, for example in tunnels, pits and around trees. Using GCS900 v11.1, contractors can now port their machine control positioning technology between dozers, graders, excavators, and soil compactors.

For excavators, Trimble GCS900 v11.1 supports a new generation of Trimble AS Series angle sensor. The new Trimble AS455 Angle Sensor is designed for use on roto-tilt bucket applications. The new angle sensor has been designed in a smaller form factor, which make it ideal for mounting in tight spaces on an excavator tilt-rotation attachment. The AS455 is gravity-referenced and measures angles in a full ±180 degree range. This capability provides the operator with the precise location of the tip of the bucket when working on tight area projects where the bucket requires increased agility to facilitate production.

Trimble GCS900 v11.1 also includes Trimble Ready™ support for the John Deere G/GP series motor graders.

Increased Support for On-Machine Data Transfer

In addition to expanded machine type support, Trimble GCS900 v11.1 delivers enhanced wireless data transfer capabilities between the construction office and the machine operator in the cab. When used with an on-machine cellular modem and the Trimble Connected Community, updated design files and production data can be wirelessly transferred between the earthmoving machine and the office.

New Support for Internet Base Stations

Using the new Trimble SNM930 cellular modem, Trimble GCS900 can now be used with almost any type of Internet base station or network real time kinematic (RTK) service, such as a remote base station at the site office or a Trimble VRS™ network, or other network RTK services. This allows the contractor to get increased machine utilization on smaller projects or where base station infrastructure may not be available for quick deployment.

Trimble GCS900 Grade Control System version 11.1 and the Trimble SNM930 cellular modem are expected to be available during the second quarter of 2009 through Trimble's worldwide Heavy and Highway Construction Distribution Channel.
