<p>The system for determining parameters representing the orientation of a solid in movement subject to a first vector field (A) and a second vector field (M) includes a first triaxial sensor (CAPT1) and a second triaxial sensor (CAPT2) secured to said solid to measure the components of said respective vector fields (A, M) according to the axes of said sensors, and a determining means (DETROT) for determining the rotation matrix (ROT) for the solid. Said determining means (DETROT) for determining said rotation matrix (ROT) includes: a correction means (CORR) for correcting the influence of an additional vector field of the same nature as said measured vector field; and a first calculation means (CALC1) for calculating a third vector (U) not coplanar to the plane formed by the two vectors (App, M) delivered by said correction means (CORR), and realized such that the angles of the axis system formed by the third vector (U) and the two vectors (App, M) delivered by said correction means (CORR) remain constant.</p> |
