Based on the projectile's geometry structure and movement characteristics, a non gyroscope inertial measurement technique using twelve linear accelerometers for the angular rate measurement and linear acceleration is presented. The simulation shows that the angular rate of moving projectile can be calculated directly by using this kind of measurement unit and the influence of the gravity acceleration on calculating angular rate and acceleration can be eliminated effectively. This accelerometer array inertial measurement technology can simplify the structure of the inertial measurement system and reduce the cost possibly. It is important to improve the performance of present conventional weapon.
