- Abstract
In view of the course error caused by the performance descent of the ship navigation device, the principle and mathematical model of the ship course alignment by the application of the relative measure between the azimuth and the relative bearing is presented in the paper. By the application of the error treatment theory and MATLAB simulation, the accuracy influence of the course by the relative measure on the pitch angle, the roll angle, the angle of altitude and the angle of chord is analyzed. The conclusion is that the pitch angle and the roll angle are the major factors which will influence the measured course accuracy of the relative measurement. At the berthing state, if the measured course accuracy of the relative measure wants to meet the alignment accuracy, the best meteorological condition should be selected first, secondly the pitch angle and roll angle should be pay attention, and the measurement of the angle of chord and the angle of altitude should be adjusted.
