Abstract: A sensor streamer drag body system. At least some of the example embodiments include a system having a sensor streamer towable behind a vessel in a body of water, the sensor streamer defining a defining a distal end and a proximal end, the proximal end nearest the vessel. The system further includes a drag body coupled to the distal end of the sensor streamer, wherein the drag body remains submerged while the sensor streamer is deployed. The drag body includes an inertial navigation system. The inertial navigation system is configured to determine a position of the drag body, the drag body lacking an internal GPS.

Abstract: Certain aspects of the present disclosure generally relate to motion compensation between water-borne objects, and, more particularly, to synchronizing motion between a remotely operated vehicle (ROV) and a docking station of a launch and recovery system (LARS). An exemplary method includes receiving a measurement corresponding to a particle motion in water surrounding an ROV and synchronizing motion of a docking station with a motion of the ROV based at least in part on the measurement corresponding to the particle motion.
