The invention discloses a satellite inertial integrated navigation terminal cheating method for a quadrotor unmanned aerial vehicle. The method comprises the steps that S1, an unmanned aerial vehicleflight control law is acquired, wherein according to nonlinear underactuated dynamic characteristics of the quadrotor unmanned aerial vehicle, a PID control method based on an integral backstepping method is utilized to obtain the unmanned aerial vehicle flight control law; S2, a quadrotor unmanned aerial vehicle inner loop controller is constructed, wherein the algebraic relation between an indirect control input quantity in a horizontal direction and an expected attitude angle is utilized to set up a bridge between a position controller and an attitude controller, and then closed-loop feedback control over the quadrotor unmanned aerial vehicle is realized; and S3, the quadrotor unmanned aerial vehicle is subjected to attitude control after a false satellite signal is connected into the quadrotor unmanned aerial vehicle, wherein according to the constructed quadrotor unmanned aerial vehicle inner loop controller, the influence mechanism of unmanned aerial vehicle position cheating offset on the attitude after the false satellite signal is connected into the unmanned aerial vehicle is subjected to analytical processing, and finally attitude control is performed on the quadrotor unmanned aerial vehicle. The method has the advantages of being easy to implement, capable of improving the unmanned aerial vehicle control effect and the like.
