Topcon Positioning Systems (TPS) introduces its patented Fence Antenna technology and expanded channel support in the new GR-5 GNSS receiver. The GR-5 provides industry-leading tracking sensitivity and multipath rejection in a compact and lightweight package.

In 2006, Topcon introduced the GR-3 GNSS receiver, which made the term “precise positioning” commonplace, and set the global standard for satellite signal reception and job site accuracy. The arrival of the GR-5 raises the bar again: the best just got better.

Ray O’Connor, president and CEO of TPS, said, “Topcon’s innovative Universal Signal Tracking and patented antenna technologies are the foundation of the new GR-5. With 216 channels and multi-constellation tracking, the GR-5 guarantees that an investment in Topcon’s industry-leading technology today will pay dividends into the foreseeable future.”

He added, “The GR-5 is smart and tough. It can perform any task for survey, engineering or construction with unsurpassed ease and dependability, and with its rugged I-beam design it can withstand a two-meter (six-foot) drop onto concrete. Our commitment to continuous innovation in the development advanced tracking and RTK algorithms ensures that GR-5 will deliver superior performance in the most challenging environments.”

In addition to its patented Fence Antenna™ technology, the new GR-5 receiver features also include:

-- High-accuracy RTK engine with position updates up to 100Hz

-- Integrated dual communication system with multiple radio and cellular combinations

-- Removable SD/SDHC storage card

-- Extended battery life

-- IP66 dustproof and waterproof rating

-- MIL-STD shock and vibration tolerance

-- Quick-SNAP pole mounting system

-- Bluetooth® connectivity

-- Operates with the full range of Topcon controller software packages

-- Environmentally sealed external ports

-- Precision-tuned, micro-centered antenna with full wave tracking

-- Operates with rechargeable Li-Ion or alkaline batteries

“Combining the GR-5 and Topcon FC series controllers – including full-color screens and rich graphical interfaces – with TopSURV and Pocket 3D software for survey and construction jobs respectively,” O’Connor said, “creates a powerful tool that performs the most simple or difficult tasks. This enables every user to save time, increase productivity and drop more money to a company’s bottom line.”
