Increasing the accuracy and reliability of a dynamic positioning laser system.

Abstract

Large number of vessels use a dynamic positioning system to maintain a given position of the vessel with great precision. The DGPS satellite navigation system and laser optical system are used as meters for such systems. The disadvantage of the laser optical system is the degradation and even loss of the signal during strong roll and pitching, which, due to the specifics of the vessels on which this system is installed, can lead to unpleasant consequences, environmental disaster and even human casualties. The authors: developed a method and algorithms for automatic aiming of the laser system beam to the center of the reflector; the operability and efficiency of the method and algorithms are verified by mathematical modeling in the MATLAB environment; the simulation results showed that automatic aiming of the beam to the center of the reflector can significantly improve the quality of the reflected signal, including in conditions of strong pitching and rolling, increase the reliability of the system and reduce the risk of an unfavorable situation; automatic aiming of the beam at the center of the reflector allows you to reduce the minimum and increase the maximum distance of operations.
