Abstract
The application discloses a method of determining the relative positions of a plurality of points located substantially in a common plane at or close to the surface of the sea, which method comprises deploying at each of said points an acoustic element comprising an acoustic transmitter and/or an acoustic receiver; sequentially actuating at predetermined time intervals at least a predetermined number of the acoustic transmitters and observing the responses of at least a predetermined number of the acoustic receivers in response thereto, such that all of the acoustic elements are operated at least once, whether in the transmit or receive mode or in both said modes; and subjecting the observed responses to signal processing to derive the spacing between each receiving element and each transmitting element, and hence to derive the relative positions of said points.
