A METHOD FOR DETERMINING THE GEOGRAPHICAL POSITION OF DEEP TOWED INSTRUMENTS

Abstract: Two array configurations of three shipborne hydrophones have been used to measure range and bearing of a deep-sea towed instrument with an attached sound source. One configuration employed a pontoon boom to support an array element off the shp’s beam, the other employed a cantilever boom. Instrument bearing was computed from travel time differences between array elements. Instrument range was computed from the depth of the instrument below the surface and one-way travel time from the instrument to one hydrophone of the array. The method is given with a discussion of the possible errors and the corrections for roll and pitch of the shipborne array.
