Description:
GE-920 features dual high-sensitivity u-blox F9 engines and dual RF connectors, enabling true dual-antenna operation for precise heading determination without reliance on vehicle movement. By operating simultaneously as an RTK moving base and RTK rover, the module delivers accurate real-time position and heading information, making it ideal for applications that require reliable orientation awareness. Supporting dual-band operation (L1 and L2) across multiple constellations—including GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS—the GE-920 ensures excellent satellite visibility and robust RTK performance. This multi-constellation capability enables fast convergence and highly accurate positioning, even in challenging environments where GNSS signals are weak or obstructed.Specifications
