Trimble Ag3000 Modem Now Available

When installed as part of a Trimble AgGPS Autopilot system, the quad-band GSM/GPRS (Global System for Mobile Communications/General Packet Radio Service) modem allows end users to improve machine guidance accuracy by accessing network correction signals that use Trimble VRS technology via a cellular connection. VRS network corrections are an option for endu users who require repeatable high accuracy but cannot easily access a correction signal from existing RTK (Real Time Kinematic) base station radio towers.


Trimble designed the Ag3000 to interface with Trimble Global Navigation Satellite System (GNSS) receivers, lightbars and the FmX integrated display powered by Transcend technology, a proprietary Trimble positioning capability that provides users with high accuracy, flexible solutions for the most challenging agriculture applications and environments. With a rugged enclosure for simpler in-cab installation, the Ag3000 also offers an external cell phone antenna for enhanced reception. Pricing for the modem, cabling and an external antenna is $1,495.

“Trimble VRS networks complement existing RTK base stations and allow us to provide more acres of sub-inch accuracy to the agricultural community,” said Erik Arvesen, vice president and general manager for Trimble’s Agriculture Division. “Using the Ag3000 modem, farmers located in areas with robust cell phone coverage and access to VRS networks have more choices available to improve machine guidance accuracy for their precision agricultural operations.”

The Ag3000 can access RTK signals from U.S. Department of Transportation (DOT) networks in states where they exist, such as Ohio and others. A partial directory of Trimble VRS installations can be found at: In addition to public and private networks that use Trimble VRS technology, Trimble also owns and operates Trimble VRS Now service, a subscription-based service, in select locations around the world and is constantly adding more locations.
