Abstract : This report presents methods for transfer alignment (TA) of inertial navigation systems (INS) which have been published in the accessible literature during the last three decades. Kalman filtering techniques based on linearised dynamics dominated in the literature of the subject. Methods of TA can be classified as angular rates, velocity or position matching. In each case a number of assumptions are made to ensure the validity of proposed technique. The accuracy of filters depends on the particular implementation viz. allowable maneuvers and time of TA, microprocessor used, vibration environment, inclusion of wing flexure into the model, type of application under discussion (range of missile or time of flight), quality of output from inertial measurement units, etc. Authors briefly discuss methods of in-flight transfer alignment of INS taking into account these assumptions.
