The Sokkia GRX5 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 4G cell modem. 

The GRX5 incorporates a revolutionary IMU which is calibration-free and immune to magnetic interference. This advanced technology compensates for mis-leveled field measurements out of plumb by as much as 60 degrees.
