Trimble is the leading designer and manufacturer of GPS equipment in MARINE NAVIGATION , marine survey systems and communications systems. With over 600 worldwide authorized dealers Trimble provides superior customer service and support. n 1984, Trimble gave mariners their first commercial GPS receiver. Since then it's continued to produce the most innovative products in marine navigation, marine survey systems and communications systems. Trimble navigation products range from handheld receivers to fully integrated DGPS/charting systems. Sperry Marine has selected Trimble as the preferred provider of GPS receivers. Sperry, which provides precise positioning information for commercial ship navigation, uses the Trimble NT200 and NT200D as part of their integrated navigation systems.

Trimble was awarded the U.S. Coast Guard contract to provide 326 custom NT200's, for use in the USCG's Aids to Navigation (ATON) vessels. The vessels are being used to place and maintain more than 50,000 buoys, day markers and lights throughout the U.S. coastal waters and inland navigable rivers.

The NavGraphicXL is a complete marine navigation system that includes the largest graphic display of any GPS-based marine navigation system on the market. The system, which is comprised of four easy-to-install modules, includes a ruggedized CD-ROM reader for reading digitized versions of NOAA charts. Using these charts, mariners can view real-time vessel position relative to depth contours, landmarks, hazards and buoys. Other system components include a slim, sophisticated navigation computer and a differential-ready, 6-channel GPS sensor. Mariners can use differential corrections for precision navigation with the help of the Trimble's NavBeaconXL or other differential beacon receiver. Back-lit LCD 9.5 inch display provides wide viewing angles and exceptional contrast. Three NMEA-0183 ports provide links to other navigation devices including radars, autopilots, fish finders and depth sounders.
