Abstract:
A long-term navigation method using an inertial master box (3) with which there is associated a tied frame of reference of axes Xm, Ym, Zm, mounted on a carrier for measuring its movements with respect to a geographical frame of reference of fixed directions along three axes Xg, Yg, Zg, comprising:measurement actions consisting in constantly measuring, by means of the inertial master box, an orientation of the tied frame of reference in the geographical frame of reference; positioning actions which consist in applying a sequence of cycles of eight turnings-over of the inertial master box each of which keeps the axis Ym in a direction parallel to the axis Yg, a succession of two turnings-over about the axis Xm being preceded and followed by a turning-over about the axis Zm, a succession of two turnings-over about the axis Zm being preceded and followed by a turning-over about the axis Xm.
