This paper investigates the path tracking control problem of an underactuated Unmanned Surface Vehicle (USV) based on a combination of Fixed-Time Line-of-Sight (FTLOS) guidance law and Backstepping control. Through theoretical analysis and simulation experiments, it is demonstrated that the proposed strategy enables the USV to smoothly and quickly follow the desired path, with all errors in the closed-loop system converging to a small neighborhood of the origin within a fixed time interval. Subsequently, experiments were designed using a self-developed USV control system and a virtual maritime platform. Comparisons between the FTLOS-Backstepping integrated control law and other guidance-control laws for USVs validate the superiority and effectiveness of the proposed approach.
