Abstract

An improved self-alignment scheme for strapdown Inertial Navigation System (SINS) based on the extended Kalman filter (EKF) and augmented measurements is proposed. Monte Carlo simulations show that the method provides good azimuth alignment, improved rate of convergence of azimuth attitude error and reduction in sensitivity to gyro biases.
