加速度计

Study on application and simulation of Kalman filter technology in SINS Because Kalman filter some merits, such as provided a fast and accurate method for SINS, adopting it to do initial alignment in this paper. The Kalman filter theory is introduced and the dynamic error vector equation of the initial alignment is derived at the first. Using velocity error as exterior value of observation, maneuverable characteristic that is influenced with system's observability and its degree is studied at length by do amount of simulations and experiences.
