Versatile Performance

Better things in smaller packages!

The GRX3 is compact, light and packed with the most advanced GNSS technology in a design built to withstand the harshest field environments. Using Sokkia’s advanced GNSS chipset with Universal Tracking Channels Technology, the GRX3 automatically tracks every satellite signal above – now and into the future.

All signals, all satellites and all constellations — in a compact, rugged design, with an integrated IMU and eCompass.

The GRX3 is a complete solution and versatile in many ways. It can be used for static or kinematic GNSS post-processed surveys, as a network RTK rover with the Tablet’s internal 4G/LTE cellular modem, as a UHF/FH/Longlink jobsite RTK rover, and also in Sokkia’s patented Hybrid Positioning workflow.

Top features include:

• Universal tracking technology for all satellites and constellations (GPS, GLONASS, Galileo, Beidou, IRNSS, QZSS, SBAS) covering all modernized signals
• Field tested, field ready IP67 design
• Compact form factor ideal for Millimeter GPS and Hybrid Positioning
• Revolutionary 9-axis IMU and ultra-compact 3-axis eCompass
• Integrated 400 MHz UHF Tx/Rx Radio Modem
• Integrated License free 900 MHz Radio Modem. FH915 protocol

Sokkia Integrated Leveling Technology (Sokkia TILT™)

By combining a 9-axis inertial measurement unit (IMU), along with a digital compass, the GRX3 can accurately compensate for up to 15º of tilt on the rod.
Now you can measure all the way to a building edge without using an offset. Or stretch to get an otherwise out-of-reach point.
Just as with many other Sokkia technologies, TILT™ is designed to solve real-world challenges, so your work gets easier, faster, and better.
