A robust path-following guidance and control system for a UAV is introduced. Pure pursuit guidance with a receding virtual waypoint is proposed to achieve robust path-following capability for the UAV. The system enables the UAV to recover from huge-tracking-error situations alleviating control saturation. The UAV can be equipped with robustness for any sharply curved path-following and wind turbulence circumstances. An optimal navigation constant according to a given path and a proper receding virtual waypoint position considering a UAV dynamics should be analyzed in the future.
