THE ORIGINAL INTEGRATED SURVEYING SOLUTION AND BEYOND

The Trimble R8 GNSS system is designed to support Trimble’s original Integrated Surveying solution. Combine your GPS and optical data in one job file in powerful Trimble field software such as Trimble Survey Controller. Transfer the job file seamlessly to your Trimble office software for processing.

The Trimble R8 can also be used as part of a Trimble IS Rover. Simply add a prism to the rover pole and partner the Trimble R8 with a robotic optical system such as the Trimble® S6 Total Station. This integrated solution enables you to maximize the best of both surveying techniques for even greater efficiency in the field.

Whenever you’re facing a new surveying challenge, your partnership with Trimble places the right tools and techniques, including GNSS technology, at your fingertips. Each Trimble system seamlessly integrates via shared workflows and technologies, making your everyday job site a place where the whole is greater than the sum of its parts: Welcome to the Connected Survey Site.
