Aircraft guidance control system

The invention discloses an aircraft guidance control system. The system comprises a quasi-satellite guidance resolving module, a microprocessor module and a virtual target simulation module, wherein the quasi-satellite guidance resolving module is used for providing aircraft position and speed information at the current moment for the microprocessor module when a satellite is lost; the microprocessor module is used for calculating required overload, the required overload comprises the required laterodeviation overload for correcting the laterodeviation of the aircraft, and the required laterodeviation overload is obtained by multiplying a navigation ratio, the flight speed of the aircraft and the missile-to-target line-of-sight angular rate in the laterodeviation direction; and the virtualtarget simulation module is used for giving the position of a virtual target point in real time according to the flight time after starting control and then calculating the missile-to-target line-of-sight angular rate in the
