Patent ID: 6898548

Claim:
Method for determining the position or the orientation of an object in space, in which: in all of the space where the object is supposed to be situated, a magnetic field (H i ) is produced using a plurality of N sources (S i ) (where N is a whole number at least equal to 1), the object is equipped with a magnetic sensor ( 20 ), the signal (C i (t)) delivered by the sensor ( 20 ) is processed in order to determine the respective contributions of each of the N sources (S i ) and the position or the orientation of the object is deduced from this, characterised in that: the field (H i ) produced by each source (S i ) is coded using a code including a binary sequence that is specific to this source, wherein the N different codes assigned to the N different sources are two by two orthogonal, the N respective contributions of the N sources are obtained through decodings that correspond to the N codes used in the sources.
