Abstract: A set of four axis aircraft PC monitoring system is designed. To accurately grasp the real-time attitude, position information of the four axis aircraft and to precisely control the four axis aircraft, the monitoring system is developed by the host computer to realize four axis aircraft attitude data acquisition, communication and control functions. The function design of the control system is good and friendly man-machine interface enables the user to accurately grasp the flight information of four axis aircraft flight. So four axis aircraft is controlled more accurately. Experimental verification, the monitoring system is simple and practical, stable performance, high precision, which makes the anti-interference ability of control system stronger, maintains better robustness and stability.

Key words: Four axis aircraft, Attitude data, Host computer, Monitoring system, Control interface
