ABSTRACT:
A goniotelemetry system comprises two acoustic goniometers directed along two perpendicular axes taking measurements of angles at the intersection O of the two axii, as well as a triaxial magnetometer and a magnetic field gradientmeter situated at this intersection O.
It allows to localize marine craft simultaneously from their radiated acoustic noise and from their disturbance on the ground magnetic field in order to fire underwater mines.
