Attitude Testing Based on Film Winding and Data Processing

The real time measure of rotation speed and rotation angle is to lower the shell distribution and extend the range of rocket. The theory of rotation speed measurement using Film geomagnetic winding was presented. It is validated on the nonmagnetic turntable. The mathematics model of measure rotation speed and rotation angle on fly bomb was modeled. The attitude of full trajectory is tested by stored testing and measuring device which is controlled by FPGA. The data analysis showed rotation speed and angle can exactly acquired the self rotation cannonball.
