System for measuring a magnetic field comprising a three-axis sensor for measuring a magnetic field that is able to move together with a carrier that disrupts the measurements, and associated method
First Claim
1. A triaxial magnetic field measurement system comprising a triaxial main sensor for measuring a magnetic field that can move jointly with a carrier element capable of generating at least one additional magnetic field disturbing measurements of said triaxial main sensor, said triaxial main sensor being configured to provide orthonormal measurements for a reference magnetic field in the absence of magnetic disturbances due to said carrier element, characterized in that the triaxial magnetic field measurement system further comprises means of adjustment of said triaxial main sensor comprising means for determining the reference magnetic field, said means for determining the reference magnetic field comprising a predetermined magnetic field generator or a removable additional sensor for magnetic field measurements, that can move jointly with said carrier element, and that is disposed outside said carrier element away from the additional magnetic field or fields.

Abstract
The magnetic field measurement system comprises a triaxial main sensor (1) for measuring magnetic field that can move jointly with a carrier element (2) capable of generating at least one additional magnetic field disturbing the measurements of said triaxial main sensor (1), said triaxial sensor (1) being adapted for providing orthonormal measurements for a reference magnetic field in the absence of magnetic disturbances due to said carrier element (2). The system comprises means of adjustment (5, 6, 7, 9, 4a, 4b) of said triaxial main sensor (1) comprising a removable additional sensor for magnetic field measurement, that can move jointly with said carrier element (2), and disposed outside said carrier element (2) away from the additional magnetic field or fields.
