AI Technical Summary

Technical Problem

In the existing technology, multi-rotor UAVs have difficulty achieving stable and accurate terminal guidance without the support of GNSS signals, especially in the case of missions to strike ground targets in complex electromagnetic environments.

Method used

By acquiring the line-of-sight angle information and initial throttle value from the UAV's onboard strapdown seeker, terminal guidance commands are calculated and generated, including throttle, roll angle, pitch angle, and yaw rate commands. These commands are then executed by the UAV's inner-loop controller until the target is hit, thus achieving autonomous guidance.

Benefits of technology

It achieves high-precision strikes against ground targets by multi-rotor UAVs in GNSS-free environments, is suitable for complex electromagnetic environments, is low-cost and computationally simple, and is suitable for low-cost hardware platforms.
