摘要： A method for determining positions of geophysical sensor streamers includes towing laterally spaced apart streamers maintained in relative relationship therebetween by paravanes proximate their forward ends. The streamers include spaced apart acoustic transmitters and acoustic receivers. The paravanes each include an acoustic transmitter or receiver. Signals are sent from the acoustic transmitters and are received at the acoustic receivers. Geodetic position signals are detected at each paravane. The identities of the transmitters of the received acoustic signals are determined to determine travel times of the received acoustic signals. The travel times are converted to distances between the identified transmitters and the receivers. Relative positions of the streamers are determined from the distances. The relative positions of the streamers are combined with the detected geodetic position signals to determine geodetic positions of the streamers.
