This paper describes results obtained during evaluation of a fine alignment algorithm for inertial navigation. The fine alignment algorithm is based on a full-state error model for extended Kalman filter and its purpose is to estimate random errors in accelerometers and angular rate sensors signals to improve the precision of determination of initial attitude angles. Precise determination of initial attitude is important in inertial navigation, since it is one of the most crucial sources of error during inertial data integration, which is performed to obtain velocity and position information.
