Paper Abstract

The analysis of the method for the ship deformation measurement is submitted. This method is based on the installing of the ring laser blocks in various points of the object. Kalman filter estimates the static and dynamic deformations by processing the output signals of these units. To make the mathematical model of the method more precise, influence of the gyro drifts was taken into account. Investigations of the filter sensitivity to accuracy of deformation model are carried out. The results of investigations of the filtering efficiency in various condition of the ship rocking are given.
