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. By combining this antenna with the
latest innovations in tracking algorithms, Topcon has given the
GR-5 our most highly advanced tracking performance ever! 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. See for yourself!
