The Tocpon GR-3 is the next generation RTK GPS system from Topcon

The World’s First G3 (GPS, GLONASS, and Galileo) capable GNSS receiver, and a clear indication of Topcon;s technology leadership in the satellite positioning industry. This exciting new system incorporates G3 tracking technology to track all three satellite positioning systems as well as new design features not found in any other system

Features and Benefits;

  • Digital UHF or Spread Spectrum radio
  • Advanced Rugged System Design
  • Optional Internal GSM / GPRS / CDMA Cellular Communication
  • 72 Universal Tracking Channels
  • Bluetooth Wireless Technology
  • G3 Satellite Tracking (GPS, GLONASS, and Galileo)

GPS receiver design has taken a quantum leap forward with the new GR-3. It starts with 72 “universal” channels that support all current and planned satellite positioning signals. Then there’s the micro-tuned, precision antenna capable of receiving all G3 positioning signals with Topcon’s patented center-mount radio antenna for superior signal tracking and interference reduction.

The GR-3 receiver incorporates a unique dual communication system, featuring both cellular and radio technology. Offering a 915 MHz Spread Spectrum internal Tx/Rx* or Digital UHF radio, the GR-3 can serve roles as either an RTK base or rover system. And by utilizing the optional internal GSM / GPRS / CDMA modem communication system via the easily accessible cellular SIM card slot, a user can extend their range far beyond radio capability or utilize both receivers as rover systems off a fixed base station or a network system.
