  • Methods and apparatus for node positioning during seismic survey
    Patent number: 9285495
    Abstract: Disclosed are apparatus and methods acoustic node positioning during a marine survey. In one embodiment, positions of a plurality of nodes are calibrated using acoustic transceivers. In addition, changes in the positions of the nodes are tracked using accelerometers. In another embodiment, a traveling wave is detected, and an effect of the traveling wave is projected on steering devices in a projected path of the traveling wave. Time-dependent control signals are computed and applied to the steering devices to maintain a local streamer geometry. Other embodiments, aspects, and features are also disclosed.
