| Abstract: | A method of solving the angular speed and attitude angular of high spinning projectile was proposed by accelerometers' specific force signal in existence of installation errors.A twelve-accelerometer configuration was designed,the mathematical model of solving angular speed was established in existence of the installation errors,the algorithm precision was researched by the damping Gauss-Newton method of nonlinear least squares.The simulated result indicates that the method can suppress installation errors ... |
