The simulation system based on laser ranging to vehicle （UAV） in landing stage was designed. Mechanical simulate flying parameters of unmanned aerial system which can control acurately horizontal moving of the object plate was composed by line slide rail, flat - toothed belt, AC servo - actuator etc. Position of the object plate was measured acurately by the laser ambulator. Conjuncting with precision timing function, instantaneous speed of the object plate was obtained. Parameters in horizontal direction such as velocity and position can be used to simulate those parameters in vertical direction when UAV was in landing stage. Practical results showed that the simulation system meets requirements and has good effect.
