Positioning made easy

This fully integrated dual-constellation RTK GNSS receiver brings a new level of versatility and flexibility into your precision applications. The GRX2 provides unmatched usability and versatility that’s sure to improve your performance.

And like all of our products, you can customize it to meet your needs and create your own workflows.

• Fully Scalable
• 226 Channels (GPS+Glonass+SBAS)
• Integrated UHF+Cellular+ Bluetooth®
• Voice Navigation
• Compact, Watertight, and Rugged
• RTK and Static survey operations

Fully Scalable Architecture
The GRX2 is affordable and scalable. You can start with it as a single frequency GPS only receiver and at any time add a radio or cellular modem for additional signal capability for GLONASS.

Multi-channel Support
Featuring 226 tracking channels with Universal Tracking Technology, the GRX2 has you covered. With programmable channels for tracking available signals, the GRX2 supports SBAS, QZSS, and QLL.

Triple Wireless Technologies
The three most commonly-used wireless technologies can be integrated into the GRX2 receiver. Digital UHF or FH915 SS modem (receiver/transmitter) for RTK base and rover, GSM/HSPA modem for network RTK, and MAGNET® Relay Bluetooth® modem for controller and other PCs.
