The DAF2 leverages an FPGA vision system with parallel pipelines to achieve unparalleled real-time performance. Unlike conventional GPU-based solutions, the parallel pipelines provide 0ms picture delay and a locking delay of no more than 5 milliseconds. This represents a 90% latency reduction compared to CPU or GPU architectures. Consequently, the UAV guidance module can lock onto fast-moving targets with sub-pixel accuracy even at high frame rates. Moreover, the system supports center locking mode and permits multiple corrections during the terminal phase. This ensures that even maneuvering drones remain firmly locked, enabling a reliable target tracking system for dynamic engagements. Furthermore, the FPGA architecture is firmware-based and clock-driven, meaning it never suffers from software crashes. In addition, the module meets EMC Level 4 standards and operates reliably across extreme temperatures from -40°C to 60°C. The lightweight 37‑gram module (excluding lens) measures only 38×38×10 mm, an 85% reduction compared to traditional GPU solutions. For end users, this translates into lower power budgets and easier integration into compact UAVs.

The DAF2 UAV employs an advanced terminal guidance algorithm based on a colorless Kalman filter to predict target positions accurately. Specifically, it uses proportional navigation to adjust the UAV’s flight vector in real time according to the angular velocity of the line-of-sight. As a result, the system achieves a remarkable CEP of ≤0.3 meters, making it suitable for high-speed precision strike guidance scenarios. Additionally, the module supports operation with or without external positioning information, allowing deployment in GPS-denied environments. This flexibility enhances drone terminal guidance in diverse mission profiles. Moreover, the DAF2 can track targets as small as 5×5 pixels and handle dynamic speeds up to 90km/h. The algorithm processes at frame rates of 50Hz or 60Hz depending on the variant, ensuring no lag even during rapid maneuvers. Therefore, the DAF2 UAV Visual Guidance System stands out as a compact yet powerful solution for demanding interception tasks.
