Vanguard Technology™ and Fence Antenna™
Topcon’s GR-5 represents the next generation in GNSS receiver technology.
Exclusive Tracking Technology
The GR-5 with Vanguard Technology™ provides
the latest advancements and beats the
competition in tracking behavior and overall
GNSS RTK performance.
Fence Antenna™ Technology
1
Once again, Topcon has set a new industry
standard with our state-of-the-art patented
Fence Antenna Technology. This revolutionary
new antenna design provides signal tracking
capabilities not found in any other RTK receiver.
Enhanced Sensitivity
The most significant advancement comes with
the Fence Antenna’s performance tracking low
elevation satellites. This patented
1
Fence Antenna
technology provides unsurpassed sensitivity while
simultaneously improving accuracy.
Advanced Multipath Suppression
Not only does the new Topcon 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 difficult environments
beyond any other RTK GNSS receiver.
