ABSTRACT:
A device for determining the absolute angular position of a turning device with respect to a fixed structure, including an encoder provided with a main multipolar track and a multipolar track called “top turn,” and a measurement means. The top turn track includes M singularities. The measurement means measures the angular position of the turning device with an angular uncertainty Δθ, in which the M singularities are each representative of an absolute angular position of the turning device and are distributed over the top turn track with an angular separation between each one greater than 2 Δθ.
