Topcon Announces New Geodetic Reference Receiver and Antenna


LIVERMORE, Calif., USA/ CAPELLE A/D IJSSEL, The Netherlands, October 7, 2014  – Topcon Positioning Group announces the next generation of its geodetic GNSS reference receivers and antennas – the NET-G5 receiver and CR-G5-C antenna.

Using Vanguard™ and Universal Tracking™ technologies, the NET-G5 receiver incorporates 452 channels capable of tracking the full GNSS signal spectrum, including modernized GPS, GLONASS, Galileo, Beidou, QZSS and SBAS signals. Universal Tracking has the advantage and capability to assign any visible GNSS signal to any available receiver channel.

The NET-G5 receiver is designed to work as a complete system connectivity solution, with built-in Bluetooth® and Wi-Fi, for flexible wireless communications or via standard Ethernet, serial and USB connections. Other features include: High-precision code and carrier phase measurements up to 100 Hz; Power over Ethernet (PoE) and an all new Topcon receiver Web interface with advanced receiver management features.

“Comprehensive communication support, advanced web-server capability, and extended operating times are among the new features supported on the NET-G5. Coupled with the CR-G5-C antenna, the new systems provides a powerful, interference protected network solution,” said Charles Rihner, vice president of the Topcon GeoPositioning Group.

“Whether you are installing an all-new GNSS network infrastructure, expanding or upgrading an existing network, looking for a premium campaign receiver or stand-alone RTK base station, the high-performance NET-G5 is designed to provide the most advanced reference station solution available in the market,” Rihner said.

The CR-G5-C is a full-wave geodetic choke-ring antenna designed to address evolving requirements for reference networks and infrastructure monitoring applications.  “The CR-G5 antenna has excellent vertical phase center stability over the entire GNSS frequency band, providing superior performance in tracking low elevation satellite signals,” said Rihner. “This new model employs cavity filter technology to more aggressively combat radio frequency interference in difficult environments.”
