[0053] The present invention will be described in detail below in conjunction with the drawings, such as figure 1 , 2 As shown, the steps of the present invention are as follows:
[0054] (1) Use DGPS, vertical gyroscope, angular rate gyroscope, magnetic heading, air data system, radio altimeter to form the main sensor system to measure the main navigation information of the UAV. Use fiber optic gyroscope and GPS to form a combined navigation system as a backup to provide backup navigation information for UAVs. In terms of altitude, there are barometric altitude, GPS altitude and the relative altitude of the landing stage; in terms of speed, there are airspeed and ground speed provided by GPS; in terms of attitude, vertical gyro provides pitch and roll angle, and magnetic heading angle provides magnetic heading angle; In terms of rate, the angular rate gyroscope provides three-axis angular rate; the backup integrated navigation system can provide navigation information of 12 com...
