This advanced positioning module integrates u-blox M10 GNSS technologies on a unified baseboard, delivering multi-frequency, multi-constellation support for high-dynamic applications. Designed for drones, autonomous vehicles, and precision agriculture, it achieves centimeter-level accuracy (RTK-enabled) while maintaining ultra-low power consumption. The baseboard provides unified power management, signal fusion algorithms, and industrial-grade interfaces:cite[2]:cite[6]:cite[8].
