Topcon Announces GR-5 GNSS Receiver

“The GR-5 is a next-generation GNSS receiver, built on multi-constellation integrated technology pioneered by Topcon,” said Scott Langbein, director of product marketing.

“Now with the inclusion of Topcon’s exclusive 226-channel Vanguard technology with Universal Tracking and the power of full-wave Fence Antenna technology that provides multipath rejection in difficult environment, the GR-5 operates with sensitivity, tracking accuracy and performance.”

In addition to Universal Tracking, Vanguard technology includes Quartz Lock Loop for signal processing in heavy vibration applications and Intelligent Tracking Optimization to select the best combination of available satellite signals.

Langbein said, “At any time, end-users can track all available satellite signals and be assured of getting accurate measurements regardless of environmental conditions.”

Additional features of the GR-5 include:

  • Cellular and radio: The GR-5 has both cellular and radio communications, which allows it to be used in radio-based RTK and network RTK systems;
  • Long-range UHF radio: The top-mounted radio antenna extends the range of RTK radio performance;
  • Operating time: GR-5 hot-swappable batteries are designed for full-day operation;
  • MAGNET Field: MAGNET Field software can be used with the GR-5 RTK system, providing the ability to share data to cloud storage and connect field crews to each other and the office.
