Abstract

INS/GPS requires the aircraft to maneuver for better observation of the attitude errors in in-fight alignment. However, the effect of the alignment is very bad because error of GPS signal is greater and synchronization is bad when aircraft maneuvers. A method of in-flight alignment by using true air speed aid inertial reference system output by air data system was presented. Compared with the traditional alignment, aircraft needn't maneuver, the in-flight alignment can be realized by the aircraft's uniform straight motion, thereby the alignment precision is improved and the time is reduced. Simulation proves the validity of the method above.

Key words： ADIRS; air data; true air speed; in-flight alignment
