Patent ID: 8767511

Claim:
A method for global acoustic positioning of a marine or submarine target using a global positioning antenna of the USBL or SBL type, the global positioning antenna placed on a moveable floating platform and comprising an emitting acoustic transducer, at least two acoustic sensors, an inertial navigation system with a GPS system or a Doppler velocity log DVL, and a computer, the method comprising: operating acoustic recurrences in succession at successive locations, each acoustic recurrence being operated by: emitting, by the emitting acoustic transducer, one acoustic pulse to interrogate a beacon placed on the marine or submarine target, and receiving, by the at least two acoustic sensors, a reflection of the emitted acoustic pulse; obtaining a synthetic network of acoustic sensors at the successive locations; and determining, based on the synthetic network of acoustic sensors at the successive locations, a single georeferenced position of the beacon.
