Navisys GM-M04B Industrial L1/L5 Dual-Band GNSS Smart Antenna Module with Bosch® BMM350 Digital Magnetometer | Multi-Constellation | 10Hz | Industrial Grade

The Navisys GM-M04B is a high-performance L1/L5 dual-band GNSS Smart Antenna Module designed for reliable positioning in industrial and embedded applications. Powered by the latest 12 nm AG3335 platform, the GM-M04B supports all major civilian GNSS constellations, including GPS, GLONASS, Galileo, BeiDou, QZSS, and NavIC. The integrated compass system, combined with concurrent L1/L5 dual-band reception, delivers faster and more reliable positioning while improving accuracy compared to conventional single-band GNSS receivers. The GM-M04B integrates a high-performance dual-band GNSS antenna, compass module, backup battery, status LED, and wire-to-board connector into a compact plug-and-play design, reducing system integration effort while delivering dependable performance in demanding environments.
