SOKKIA GRX3 RTK 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.
