Abstract
The present invention concerns a system for contactless determination of the position and orientation of a first mobile object (M) relative to a reference mark (R) carried by a second fixed or mobile object (P), in a disturbed electromagnetic environment comprising a transmitting antenna (E) with ferromagnetic cores (E-) having magnetic permeability higher than 10, incorporating sensors (E-) for measuring the magnetic field Xactually emitted by the axes of the ferromagnetic cores. A means (-) for extracting the signal correlated with the ambient noise X(T−KT)—from the sensors (Sb) fixed in the platform (P), forms, with measurement Xof the emitted magnetic induction, a complete model of the measured fields, making it possible to extract, without errors, the six parameters relative to the field model without disturbances.
