A system of independent recording units that can be used to form an arbitrarily large acoustic array is described. Position of units and timing of signals are obtained from Global Positioning System (GPS) with precisions within 2.5 m and 50 microseconds, respectively. An integrated hardware and software solution is presented and results reported from a four-unit feasibility test in shallow water. Sound sources at a distance of 2 km were located within 2 to 138 m of GPS-derived positions. (C) 2001 Acousrical Society of America.
