Abstract :
In this paper, a physical model device of twelve-accelerometer´ inertial measurement unit is designed and manufactured to solve the High-speed projectile attitude angular estimation´s low precision´s problem. And proposing methods to calibrate misalignment angle and position installation error. According to the mathematical model of angular speed solving with the installation errors, nonlinear least squares is used to compensate accelerometers´ installation errors. Simulation result shows that this method can suppress installation errors effectively and acquire attitude of high efficiency. This method has some actual application value.
