Sokkia GRX3 GNSS Receiver

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.
