Abstract
A system for acoustically positioning a noisy platform. An array of transponders, adapted to be deployed in a region of water, is provided. A transducer is mounted on the noisy platform and another transducer is mounted on a relatively quiet vehicle tethered to the platform. A first means is provided for transmitting acoustical energy from the transducer on the noisy platform to said array and from said array to said transducer on said vehicle for measuring the distance from said noisy platform to said quiet vehicle via said transponders in said array. A second means is provided for transmitting acoustical energy from the transducer on said vehicle to said array and back to said vehicle for measuring the distance said vehicle is from the transponders in said array. Calculating means is coupled to said first and second means for determining the location of said noisy platform relative to said array.
