ABSTRACT:
A magnetic coupling device in which two assemblies of three coils are attached respectively to two mechanically independent bodies and form a radiator assembly and a sensor assembly. Each assembly defines a cartesian coordinate frame and is associated with a switching circuit controlled so that the radiator coils are excited successively and separately by the same alternating-current wave and so that the sensor coils are connected separately and successively to processing circuits during each excitation stage of a radiator coil. The processing circuits comprise a synchronous demodulator, a coherent integrator and a control loop for reducing the induced signal received to zero and measuring the corresponding field component. This measurement is performed by an ancillary computer which determines the Euler angles.
