Trimble Connected Site Solutions Extend the Range and Flexibility
of GNSS on the Construction Job Site

Communication Tools Make it Easier and More Economical to
Use GNSS-Based Positioning Solutions on the Construction Site

Munich, GERMANY, April 19, 2010 — Trimble (NASDAQ:TRMB) today introduced new Trimble® Connected Site™ solutions that extend the range of base station correction sources and make it easier to use GNSS-based positioning systems on the construction job site. Using the innovative Trimble Internet Base Station Service (IBSS) and the new Trimble SNM910 field cellular modem, a contractor can easily connect machines, vehicles and rovers to a base station, whether the base station is located in the office, on the local site, or on a site kilometers away.

The announcement was made today at Bauma 2010, the world's largest construction equipment exposition.

Trimble Internet Base Station Service Uses the Internet to Extend GNSS Coverage

The new IBSS provides GNSS correction information over the Internet using cellular services instead of relying solely on site radio communications, which can be subject to range limitations and black spots. IBSS is an add-on subscription to Trimble modular base stations and all rovers. To leverage the service, contractors simply connect their base stations to the IBSS using a wireless Local Area Network (LAN) or cellular modem technology to provide GNSS corrections over longer distances than normally possible with radio and repeater technology. The Trimble SNM910 cellular modem is designed specifically to connect a Trimble base station to the Internet and the IBSS server in situations where a wired LAN connection is not practical or desirable.

The new service extends precise GNSS coverage to remote or offsite project areas such as borrow pits, dump sites or other projects within a 30 kilometer (18 mile) range and provides more flexibility for the setup of GNSS infrastructure on large projects. This is especially useful for companies running multiple projects within a 30 kilometer (18 mile) radius to solve radio outage problems on large projects or in difficult terrain. Location RTK accuracies can be achieved using IBSS at greater distances. This is useful for new site reconnaissance or for initial site works such as setting site limits, clearance lines or silt fencing and topsoil stripping without the need to set up a local base station.

Rover users or machine operators using any Trimble Construction GNSS receiver can connect directly to the Internet service and select the closest available GNSS base station from a list on the IBSS server.

Using a wired LAN or cellular connection to IBSS, contractors can also select a remote IBSS base station and rebroadcast the RTK correction stream from that base to rovers or machines in the vicinity. This allows the radio rebroadcaster to be located in a static location where good cellular coverage is available and allows multiple GNSS rovers and machines to operate anywhere within radio range. This set-up reduces the need for multiple modems and cellular service plans connecting each asset individually to the IBSS server, or long radio repeater chains, saving the contractor considerable costs while also providing more reliable service in difficult coverage areas.

Alternatively, contractors can use the same LAN or cellular connection to rebroadcast GNSS corrections from a Trimble VRS™ network and remove the range limitations of radios for precise or location GNSS operation.

As part of Trimble's commitment to delivering Connected Site solutions, the IBSS subscription is delivered through the Trimble Connected Community, an information management system for contractors to more efficiently communicate and collaborate. A base station using IBSS is fully under the contractor's control through the use of a secure login and password and can be shared between multiple project partners and job sites using the Trimble Connected Community.

The Trimble SNM910 Cellular Modem and Internet Base Station Service are expected to be available through Trimble's worldwide Heavy and Highway Construction Distribution Channel in the second quarter of 2010.
