Abstract
This article describes the main problem of a seismic crew operations in transit zones with ocean bottom cable (OBC) equipment. Required accuracy ensuring of receiving equipment layout. Online methods of vessel track course corrections at the time of pickup equipment is describes. This technique has significantly reduced the time of seismic work production. During of the seismic works, acoustic positioning is not carried out for all receiving points often. This primarily due is equipment high cost. Increasing accuracy of positioning sensors without acoustic positioning is carried out using the methods of interpolation receiver points coordinates, taking into account track of the vessel. Comparison of standard procedure of linear interpolation, as well as rationale use procedures for adjusting the receiver point position on the first break picking entry during the work in the OBC 3D modification.
