Trimble R7 Base Or Rover Receiver
The Trimble® R7 GNSS System is a multi-channel, multifrequency GNSS (Global Navigation Satellite System) receiver and UHF radio combined in one exceptionally rugged unit. The Trimble R7 GNSS combines advanced receiver technology with proven system design to provide maximum flexibility, accuracy, and productivity.

Powered by the enhanced RTK engine, Trimble R-Track™ technology in the Trimble R7 GNSS supports the GPS Modernization signals L2C and L5, as well as GLONASS. The R7 GNSS is also capable of using the three levels of OmniSTAR1 positioning – OmniSTAR HP, OmniSTAR XP and OmniSTAR VBS.

Its ability to track more satellites—both GPS and GLONASS—means Trimble R-Track can help to improve field productivity, and the resulting postprocessed or RTK solution is enhanced. The new and coming L2C and L5 will also improve the solution, plus these signals are more easily acquired and tracked in challenging GPS conditions.

Investing in the power of Trimble R-Track prepares you for future GNSS capabilities. Trimble, already proven in GPS, will continue to lead in additional GNSS support.

The overall design of the Trimble R7 GNSS system has been tried, tested, and proven in the field.

Flexible Separate Antenna Options
Use the Trimble® Zephyr Geodetic™ 2 ground plane antenna3 to minimize signal multipath at the Trimble R7 GNSS base, providing the “cleanest” data. As a rover, the modular Trimble R7 GNSS with Trimble Zephyr™ 2 antenna is extremely flexible: Carry the receiver on the pole, wear it in the purpose-built Trimble backpack, or drive with the Trimble R7 GNSS inside your vehicle. The Trimble R7 GNSS supports the way you want to work.

New Bluetooth Wireless Communication
For extra convenience and fewer cable hassles, the Trimble R7 GNSS includes Bluetooth for wireless connection to a Trimble controller, such as the Trimble® TSC3 Controller.

Exceptionally Rugged and Lightweight
The GNSS receiver and internal UHF radio are fully protected from water, dust, and shock inside the unit’s full metal jacket. This field sturdiness makes the Trimble R7 GNSS ideal for tough environments.

The Trimble R7 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 Access™, then transfer the job file seamlessly to your Trimble office software, such as Trimble Business Center, for processing.

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 Site.
