Abstract
The invention relates to a device () for measuring the angular errors in the inclination of a real axis of rotation () of a rotary element (), the device comprising control electronics () controlling the rotation of the rotary element () about its real axis of rotation (), a first and a second rotation sensor () for obtaining angular velocities about two measurement axes () which are orthogonal to one another and both orthogonal to the real axis of rotation (), a third rotation sensor () making it possible to obtain the angular position and angular velocity of the rotation element () about its real axis of rotation (), at least two of the aforementioned sensors being inertial sensors making it possible to obtain projections of the vector of the speed of rotation of the Earth onto at least two axes of projection, an acquisition unit (), a measurements-storage memory (), a computation unit () configured to compute, from the angular positions and velocities obtained from the aforesaid sensors, the angular errors in the inclination of the real axis of rotation () of the rotary element ().
