New Trimble GPS Receiver Capabilities Give Construction Professionals
More Robust Signal Tracking for Greater Efficiency

Faster Initialization and Improved Receiver Performance in Areas with Limited Satellite Reception
Deliver High Accuracy Positioning Across the Jobsite to Eliminate Downtime

SUNNYVALE, Calif., March 20, 2009 — Trimble (NASDAQ: TRMB) introduced today a new version of its Global Positioning System (GPS) receiver firmware. New capabilities in the GPS firmware 4.0 provide faster initialization and improved receiver performance that significantly benefit construction contractors using GPS receivers in the Trimble® Site Positioning Systems (SPS) series.

Improved Satellite Signal Reception in Challenging Construction Environments

The enhanced Real Time Kinematic (RTK) engine of version 4.0, which powers Trimble R-Track™ technology, provides faster initialization and improves receiver performance in areas with limited satellite reception. This includes jobsites where satellite signals are obstructed by tall buildings, high quarry walls, or tree canopy. When RTK correction signals are intermittent or marginal, the new RTK engine provides improved precision estimations. This unique capability allows a Trimble GPS receiver to continue working at reduced accuracy even after an RTK signal is interrupted. It is ideal for jobsite positioning and measuring applications in locations where the highest accuracy is neither achievable nor required.

For contractors operating multiple jobsites with limited base station infrastructure availability, the new RTK engine allows SPS receivers operating at jobsites located at greater ranges from the base stations to have rapid initialization and improved vertical accuracy. This allows contractors to meet the requirements for initial site operation — such as clearance, setting right of way lines and initial stakeout for earthworks.

New Correction Protocol for Efficient Use of Satellite Signals

Trimble GPS receiver firmware 4.0 utilizes a new proprietary protocol, CMRx, for corrections transmitted by a GPS base station. The ability to track more satellite signals provides contractors using Site Positioning Systems with the ability to maximize the use of all available satellite signals and constellations at both the base station and the rover for increased up time in a variety of jobsite environments.

Through this development, Trimble is once again pioneering improvements in the industry-standard RTK technology through a significant evolution of its existing CMR and CMR+ standards for correction message protocol, preparing the industry for future satellite positioning constellations and signals. Trimble first developed RTK technology in 1994.

Efficient GPS Receiver Management through the Trimble Connected Community

A new feature in Trimble GPS receiver firmware 4.0 enables users to operate and manage their Trimble GPS receivers through the new Trimble Connected Community (TCC). An optimized version of the popular Web User Interface (UI) of the SPSx81 Smart GPS Antennas and SPSxx1 Modular Receivers can be placed on a TCC site. This creates an instant dashboard displaying the status of potentially all connected receivers in an organization, as well as providing access to the full receiver Web UI for remote set-up, configuration, and more. Contractors can utilize the corrections over a radio or cellular/Internet connection, extending coverage into radio blackspots, new areas of development, or neighboring jobsites.

Managing a GPS receiver through the Trimble Connected Community enables users such as site managers and project supervisors to work more efficiently by remotely accessing receivers from wherever they are, for example, using a Trimble Tablet rugged PC. They can also receive e-mail notifications of receiver status without having to log on to their Trimble Connected Community site.

Trimble GPS receiver firmware version 4.0 is available today for the Trimble SPS series GPS receivers through Trimble's worldwide Heavy and Highway Construction distribution channel.
