Features

Exceptional Versatility in a compact design

The Sokkia GRX3 is smaller, lighter, and packed with the most advanced GNSS technology in a design built to withstand the harshest field environments.  All signals, all satellites and all constellations —  in a compact, rugged design, with an integrated IMU and eCompass.

Sokkia Tilt Technology

Incorporates a revolutionary 9-axis inertial measurement unit (IMU) and ultra-compact eCompass, which compensate for mis-leveling up to 15 degrees.

  • Sokkia Tilt Technology 
  • L Band Ready Technology
  • 226 Universal Tracking Channels (GPS, GLONASS, Galileo, BeiDou, IRNSS, QZSS, SBAS)
  • Integrated 400 MHz UHF and SiteCom™ radios
  • Fusion Positioning™ technology
