IMPROVEMENTS TO METHODS FOR ALIGNING INERTIAL NAVIGATION SYSTEMS

The invention relates to a method for aligning an inertial navigation system borne by a static or quasi-static carrier, wherein: a plurality of alignment processes that are dimensioned for a pluralityof amplitudes of movements of the carrier are implemented simultaneously with different alignment observation durations; a minimum observation duration that corresponds to the alignment observation duration for which the consistency of the alignment information obtained by means of alignment processes dimensioned for a given movement amplitude of the carrier is determined; and the alignment information is determined depending on alignment information determined for this minimum observation duration. The invention also relates to an associated inertial navigation system. 本发明涉及一种用于对由静态或准静态载体携带的惯性导航系统进行对准的方法，其中：在不同对准观测持续试下的情况下，同时执行多个对准过程，所述多个对准过程是针对所述载体的运动的多个幅度设置的；确定最小观测持续时间，所述最小观测持续时间对应于对准信息的一致性被确认的对准观测持续时间，所述对准信息是借助于针对所述载体的运动的给定幅度设置的对准过程来获得的；并且根据针对所述最小观测持续时间确定的对准信息来确定所述对准信息。本发明还涉及相关的惯性导航系统。
