Abstract:

The in-flight yaw and spin motion of artillery shells and other munitions is frequently measured by the use of optical sensing and standard RF telemetry techniques. The standard system that is used is called the Yawsonde. The technique that has been investigated replaces this device with an inertial sensor package. This program has determined that all three characteristic rates of motion -- spin, nutation, and precession -- are directly calculable from each of several inertial sensor configurations. In addition, there are currently available components that are suitable for this application and can survive the launch environment.
