Abstract

Centrale inertielle comportant un cœur inertiel (3) relié à une unité de commande (50) et monté sur un support (1, 2, 4, 5, 6, 7, 8, 14) de maintien du cœur dans un repère inertiel (Xi, Yi, Zi), le cœur comportant au moins deux gyroscopes (9, 10, 11) montés relativement l'un à l'autre pour avoir des axes sensibles sensiblement perpendiculaires l'un à l'autre, caractérisé en ce que le cœur comprend des moyens de pivotement de chaque gyroscope autour d'un axe de pivotement (R1, R2 R3) sensiblement perpendiculaire à l'axe sensible du gyroscope concerné, l'unité de commande étant reliée aux moyens de pivotement pour commander ceux-ci et étant agencée pour effectuer des mesures angulaires au moyen des gyroscopes dans au moins deux orientations de ceux-ci autour de l'axe de pivotement concerné. Procédé de mesure angulaire comportant une étape d'orientation des gyroscopes.
