The UM982V6 integrates Unicore UM982 dual-antenna RTK module and RMS3100 high-precision magnetometer for centimeter-level positioning and heading control. Designed for autonomous drones, agricultural robotics, and industrial navigation, it delivers concurrent multi-GNSS processing with 20Hz RTK+Heading output via TTL interfaces. The module features ultra-compact design, industrial-grade resilience, and plug-and-play compatibility with major flight controllers:cite[1]:cite[2].
