Abstract
This invention provides a shock mitigation means that attenuates the high frequency energy transmitted to the floating element of an inertial measurement unit (IMU) device in a cannon launched guided projectile or cannon launched munition improving the ability of the IMU to survive the extreme forces of such cannon launched environment. The invention utilizes a crushable foam mitigator located in the IMU device's housing to interfere and apply a compressive force to the floating element of the IMU device, plus a rubber pad attenuator element placed above the foam mitigator to further tailor the transmission of shock energy to the floating element in the IMU device.
