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.
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.
