FILTERING A SIGNAL FROM NOISE AT A SINS COARSE INITIAL ALIGNMENT
SCIREA Journal of Information Science and Systems Science
The possibilities of using the Kalman filter for cleaning (filtering) signals from gy-roscopes and accelerometers of a strapdown inertial navigation system (SINS) with a rough initial alighnment on a fixed base are considered. For this, algorithms for averaging filters with forward and backward computations (forward and backward filters) are proposed. It is shown that with a relatively short recording of the signal (30 s), in comparison with the simple average of the signal, it is possible todoi:10.54647/isss12146 fatcat:3kgatcolrnamfm75745fab7jjq
