Trimble Introduces Quadband GSM/GPRS Version of the TrimTrac Locator

Portable, Affordable and Ready-to-Use Device Offers Worldwide Asset Monitoring and Control

SUNNYVALE, Calif., March 9, 2006 Trimble (NASDAQ: TRMB) introduced today its newest member of the TrimTrac™ locator product family. The TrimTrac 1.5 locator is a small, lightweight asset-monitoring device that requires little, if any, installation when used in its battery-powered configuration. Hardware and setting options allow the device to be configured to meet a variety of demanding installation and operational requirements. Like the original TrimTrac locator, motion-based reporting continues to be an important tool in minimizing power consumption and recurring communication costs.

Trimble's TrimTrac 1.5 locator, along with offerings from multiple location-based Application Service Providers (ASPs) that are compatible with the original TrimTrac locator, will be showcased at CeBIT, the world's largest trade fair for digital IT and telecommunication solutions, March 9-15 in Hanover, Germany.

Cost-effective, Universally Available Communications
The TrimTrac 1.5 locator supports all GSM frequencies (900/1800MHz and 850/1900 MHz) to take full advantage of cost-effective GPRS data rate plans and the near universal roaming capability of SMS text messaging. The TrimTrac 1.5 locator takes advantage of both technologies by automatically selecting GPRS wherever such service is available, while relying upon SMS text messages as backup when outside GPRS coverage. This helps minimize recurring communication costs while allowing the greatest coverage possible.

Hardware Options, Expanded Capabilities
A variety of hardware options are available to enhance the suitability of the TrimTrac 1.5 locator to particular application requirements. These options include optional plug-in modules plus a miniature external GPS antenna that allows for more discrete, protected installation of the TrimTrac 1.5 locator.

Two optional plug-in modules are offered: vehicle adapter and control modules. Both modules provide connection to external 9-32 VDC power to eliminate the need to change batteries and can monitor inputs of three different priority levels. The control module also provides two outputs that can be used to control other on-board devices or systems, such as door locks, immobilizers and remote start systems.

Enhanced Functional Capabilities
Position reporting triggered by motion continues to be an important attribute of the TrimTrac 1.5 locator and it is backward compatible with applications developed for the first generation TrimTrac; however, a range of powerful new functional enhancements now augment this basic capability with the TrimTrac 1.5 locator. These functional enhancements include 1 Hz GPS operation, on-board geofence enforcement, scheduled hours of operation, multiple runtime meters, start/stop reporting mode, and more.

Availability
The TrimTrac locator 1.5 is expected to be available in limited volumes in the second quarter and in quantity in the third quarter of 2006 through Trimble's Component Technologies authorized distributors and service provider network.
