B8 is specifically designed for multi-rotor aircraft operating under high-vibration and heavy-load conditions. It features three sets of industrial-grade MEMS IMUs and an integrated shock absorption design. Coupled with a magnetometer and barometer architecture, it incorporates multi-source fusion algorithms to achieve centimeter-level positioning, emergency protection in all fault scenarios, fully autonomous operation with thousands of waypoints on a single flight path, and long-duration on-board data closed-loop storage. It is the safe and optimal choice for small and medium-sized multi-rotor aircraft operating in high-vibration environments.
