Weapon Orientation Sensor for Simulated Tactical Engagement Training

Weapon orientation systems work in a Line-of-Site (LOS) manner using a Multiple Integrated Laser Engagement System (MILES). The Army is seeking a non-LOS solution for long range weapon orientation. High end Inertial Measurement Units (IMUs) provide the required accuracy for this functionality but, are unsuitable because of their size, power draw, and cost. The Army is requesting a low cost IMU that is capable of determining absolute heading with no calibration procedures. Additionally, it must be able to mount to a soldier"s weapon and be ultra low power. Cybernet Systems Corporation is proposing a solution to non-LOS weapon orientation problem using a self calibrating sensor that is based on our current Inertial Measurement and Magnetometer Module (I3M). It will collect accelerometer, gyroscope, and magnetometer data in pitch, roll, and yaw and will use known constant inertial movements to continuously keep the device calibrated.
