The BK-009Pro-8CH GNSS anti-jamming system is a compact and high-performance GNSS anti-jamming navigation module developed for civilian and industrial UAVs. It supports dual-frequency reception of BeiDou B1/B3 and GPS L1/L2 signals, offering superior positioning accuracy and reliability even under strong electromagnetic interference.
This system integrates an antenna array, anti-jamming components, and GNSS receiver within a single lightweight housing, providing 360° full-sphere interference suppression and strong resilience against multiple interference sources. Ideal for unmanned aerial, ground, or marine platforms, it ensures the security and continuity of PNT (Positioning, Navigation, and Timing) data.
