Method and system for determining geodetic positions of towed marine sensor array components

A system for determining geodetic positions of a plurality of marine geophysical sensor streamers, comprising:

• a plurality of laterally spaced apart sensor streamers each functionally coupled at
• a forward end thereof to a towing vessel;
• a paravane disposed laterally outwardly on each side of the plurality of streamers, the paravanes configured to maintain lateral selected separation between adjacent streamers;
• a plurality of acoustic transmitters disposed at spaced apart locations along the streamers, the transmitters configured to transmit signals enabling identification of each of the transmitters from which the signals originate;
• a plurality of acoustic receivers disposed at spaced apart locations along the streamers, the receivers configured to receive the signals from the transmitters;
• a geodetic position signal receiver, and at least one of the acoustic transmitters and the acoustic receivers disposed on each paravane;
• at least one processor configured determine identities of transmitters of received acoustic signals and travel times of the received acoustic signals, the processor configured to convert the travel times to distances in both an in-line direction along streamers between transmitters and acoustic receivers in the same streamer, and in a cross line direction between transmitters and acoustic receivers in different streamers, the processor configured to determine relative positions of the streamers from the distances, the processor configured to determine geodetic positions of the streamers from the relative positions and the signals detected by the geodetic position signal receiver on each paravane.
