    GRX2 Features :

    The GRX2 receiver is a fully integrated dual constellation receiver, antenna, radio, and optional cellular modem. In addition, the integrated Bluetooth module, now enhanced for better performance, is designed into a rugged magnesium alloy body.


    Fully Scalable Architecture

    GRX2’s scalable architecture maximizes your return on investment. It allows you to start with an L1 GPS receiver with a minimal initial cost, which can be upgraded to L1 GPS+GLONASS, to L1/L2 GPS, up to 226-channel L1/L2 GPS+GLONASS receiver at any time you need.

    226 Channels for GPS + GLONASS + SBAS

    • 226 tracking channels with Universal Tracking Technology are available for GPS, GLONASS and SBAS signals tracking.
    • Supports GPS L2C signals.

    Other Hardware Features :

    • 22 status LED displays are exceptionally viewable even under bright sunlight.
    • Data storage in popular SD cards. Large capacity SDHC cards are also supported.
    • IP67 dust/water protection
