Description The HB10 is a GNSS positioning and orientation RTK receiver designed for industry drones, unmanned systems, precision control, and earthquake monitoring — powered by a Septentrio AsteRx-m3 . It supports multi-constellation GNSS tracking, dual-antenna heading output, ultra-low latency, high refresh rate, and stable tracking during high-frequency vibration and fast movement. Built-in anti-interference technologies ensure reliable operation in complex electromagnetic environments.
