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.
