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 with GPS and GLONASS constellation integration, Topcon continues to lead all other manufacturers with the most sophisticated receiver technology and design.
GNSS Satellite Tracking Optimization with Vanguard™ Technology
The GR-5 features the multi-constellation 226-Channel Vanguard GNSS chip with Universal Tracking Channel Technology. This patented technology uses flexible and dynamic tracking methods to automatically select and track any available satellite signal enabling Topcon’s users to receive the maximum number of signals and measurements at any given time.
The GR-5 is not only capable of receiving signals from fully operational GPS and GLONASS constellations, but also has ability to support all planned signals from developing systems like Galileo, Beidou (BDS) and QZSS. With current and developing satellite constellations, Universal Tracking Channel Technology optimizes GNSS signal tracking to guarantee maximum satellite geometry and availability.
Enhanced Sensitivity with Patented Fence Antenna™ Technology
Topcon’s patented Fence Antenna design brings to the GR-5 superior signal reception and advanced multipath rejection in difficult environments. This technology provides to users a more robust and cleaner signal tracking which means unparalleled results.
Advanced Multipath Suppression
Not only does Topcon's Fence Antenna™ outperform other RTK receivers with enhanced sensitivity, but also provides multipath rejection characteristics that gives the GR-5 a level of tracking performance in demanding environments beyond any other RTK GNSS receiver.
In side-by-side tests with other RTK GNSS receivers the latest 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.
With Vanguard Technology™, Universal Tracking Channel and Fence Antenna™, the GR-5 is designed to deliver ultimate filed performance even in challenging environments while maintaining unmatched accuracy, speed of initialization and fix reliability for RTK solution.
In addition to advanced technologies, the mechanical design of the GR-5 makes it incredibly reliable, ergonomic, and durable. Guaranteed rugged, the GR-5 is the best GNSS receiver available in the market. It all sums up to... More Performance. More Accuracy. More Productivity. See for yourself!
