SYSTEM FOR POSITIONING A WIRE USING SENSOR INFORMATION OF DISCLOSURE A system for determining coordinates for nodes on a wire secured to tow lines of a floating vessel for analyzing geological formations is provided. The system can include sensors in 5 communication with a processor to determine the coordinates of nodes and provide azimuths tangential to the wire. A library of nominal values for third, fourth, or fifth order polynomial coefficients, a library of known distances along the wire, and a library of preset limits can be stored in a data storage. The system can include computer instructions to receive sensor information, compute bearing, reorient the coordinates, rotate the azimuth, construct a third, 10 fourth, or fifth order polynomial algorithm, compute the azimuth, form a residual, compute updated differences until the residual is within preset limits, calculate local coordinates for nodes, and rotate the local coordinates from the local coordinate system to the projected coordinate system. is 6306140_1 qCV3 LUz j CE). |
