The DAF2 UAV visual guidance system stands out. It uniquely combines a colorless Kalman filter, low-latency target tracking, and proportional navigation algorithms. These algorithms work in concert to predict target positions with high accuracy, even during high-speed maneuvers. However, the system’s FPGA hardware-acceleration architecture is the true differentiator. Unlike traditional CPU or GPU-based solutions that suffer from processing bottlenecks, the FPGA executes parallel video pipelines. This achieves 0ms picture delay and a locking delay of just ≤5ms. That represents a 90% improvement over conventional platforms. Moreover, the FPGA’s clock-driven parallel pipeline eliminates software crash risks, ensuring ultra-high reliability even under extreme conditions. Consequently, the DAF2 operates flawlessly in temperatures ranging from -40°C to 60°C and meets EMC Level 4 standards. With a core module weighing only 18g and consuming ≤2W, it reduces SWaP by 85% compared to GPU solutions. That makes it ideal for lightweight tactical drones. This fusion of low-latency tracking and FPGA acceleration ensures precise target locking. The DAF2 can lock onto targets as small as 5×5 pixels. Then it maintains pursuit at speeds up to 90 km/h, delivering precision strike accuracy. Indeed, FPGA acceleration is the cornerstone of its speed advantage.

The DAF2 UAV visual guidance system is available in three models. These are DAF2 A, DAF2 HD, and DAF2 DU, each optimized for different requirements. The DAF2 A offers a vehicle locking distance of 300m and a resolution of 720×576. This makes it suitable for close-range missions. Meanwhile, the DAF2 HD extends vehicle locking distance to 800m. It features 2560×1440 resolution and a 66°×40° field of view, providing exceptional situational awareness. The DAF2 DU variant adds an infrared camera with a 13mm focal length. This enables infrared guidance for nighttime and low-visibility conditions. The infrared guidance capability extends operational effectiveness to 24/7 surveillance. It locks onto vehicles at 800m (visible) and 500m (infrared). Additionally, all models share critical features. These include ≤5ms latency, support for CRSF/SBus/MavLinkv2 protocols, and compatibility with BetaFlight, INVA, APM, and PX4 firmware. Notably, they operate with or without external positioning information, offering flexibility in GNSS-denied environments. With a minimum tracking size of 5×5 pixels, the DAF2 series captures even the smallest targets. Its 90 km/h speed capability ensures robust precision strike performance across counter-drone and surveillance missions. Finally, low-latency tracking across all DAF2 models ensures that even at 90 km/h, the system never loses lock.
