Aimed at characteristics of transfer alignment on a moving base-guided vehicle, a kind of accuracy estimation method was proposed. The navigation accuracy was mostly caused by attitude error and the simplified relation between transfer alignment error and velocity error was derived according to velocity error formula. After transfer alignment, the system entered into the navigation under similar flight and velocity error was measured in short time, further attitude alignment error was anti-derived. The yaw angle error was estimated by calculating reproducibility of the difference between major and slave inertial navigation system. Pitch and roll angle error were estimated by calculating reproducibility of velocity error between major and slave inertial navigation system. Experiments data show that the alignment accuracy meets the target and it is suitable for engineering application.
