The Topcon GR-5 Represents The Next Generation In GNSS Receiver Technology
Topcon is proud to be the world leader in advanced satellite positioning technology. As the original pioneer of dual-constellation and G3 triple constellation integration, Topcon continues to lead all other manufacturers with the most sophisticated receiver technology and design.


Topcon’s G3 Technology Was The First To Combine All Three Of The Original Positioning Systems - GPS, GLONASS, And GALILEO 
Although commercial use of Galileo continues to be years away, Topcon continues its commitment to develop technology to utilize ALL signals from ALL satellites. Not only is Topcon committed to the GPS, GLONASS and GALILEO satellite systems, but also to all precision signals from the developing Chinese COMPASS system, Japan’s Quasi-Zenith Satellite System (QZSS), and India’s IRNSS system. If there is any operational advantage of combining new systems and signals, you can count on Topcon to continue to lead the industry.

The New GR-5 Receiver Is The Next Step In The Continuing Development Of The Latest, Most Advanced Receiver
Technology Available. Building from the tremendous success of the world’s first G3 RTK receiver, the Topcon GR-3, the new GR-5 provides the latest technological advancements with the same powerful performance our customers have grown to demand.

One Look At The New GR-5, And You Notice The New, Advanced Antenna Design 
This patented1 Fence AntennaTM Technology Provides industry- leading tracking sensitivity and multipath rejection in a compact and lightweight package.

The GR-5’s tracking capabilities are not only state-of-the-art, but also deliver unmatched value to our customers by providing accuracy levels superior to other RTK systems in difficult environments. While other systems sacrifice accuracy for tracking performance, the GR-5 gives you the best of both!

The New GR-5 Design Didn’t Stop Simply With New Antenna And Tracking Technologies
 The GR-5 Also Boasts Numerous Advancements such as: an increased number of channels, extended battery life, expanded internal memory options, new internal modem design, internet-compatible firmware, and much, much more. It all sums up to... More Performance. More Accuracy. More Productivity.

Topcon’s New, Patented Fence Antenna™  Technology Leadership
Once again, Topcon has set a new industry standard with our state-of-the-art Fence AntennaTM Technology. This revolutionary new antenna design, first presented in a technology paper at the ION GNSS International Conference in 2009, provides signal tracking capabilities not found in any other RTK receiver.

Enhanced Sensitivity
The most significant advancement comes with the Fence Antenna’sTM performance tracking low elevation satellites. This patented1 Fence AntennaTM technology provides unsurpassed sensitivity while simultaneously improving accuracy.

Advanced Multipath Suppression
Not only does the new Topcon Fence AntennaTM outperform other RTK receivers with enhanced sensitivity, but also provides multipath rejection characteristics that gives the GR-5 a level of tracking performance in difficult environments beyond any other RTK GNSS receiver.

Side-By-Side Tests
In side-by-side tests with other RTK GNSS receivers the new Topcon GR-5 with patented Fence Antenna™ Technology outperformed the competition in tracking behavior and overall RTK performance, and continues to lead the industry RTK radio range.
