Method of alignment independent of the inertial unit for on-board instrument capable of equipping a 371 and on-board instrument able to use such a process

摘要

The present invention relates to a method of alignment autonomous (40) of the inertial unit for on-board instrument capable of equipping an aircraft, characterized in that it comprises the following steps: - monitor the development of a movement of the inertial unit for the alignment (40), - suspend the alignment (40) of the inertial unit in the case of occurrence of movement, - take the alignment (40) of the inertial unit to the disappearance of the mouvement.l' invention has the advantage of optimizing the duration of the alignment in the extent that it can be carried out for all the periods in which no motion of the inertial unit is detected, but only during these periods. It makes possible a rapid and reliable alignment of the inertial unit.
