摘要
Abstract
The GPS data was recorded on the way to QZ8501 crash zone in Java Sea by"Nanhaijiu 101", and the length of the way was 330 km. The GPS data was processed to remove the gross error. The smoothed data was got after wavelet analysis. According to the DTU10 model, tide data of 4 stations was forecasted on the route. The tide of the vessel on the route was got by the nearest time and distance principle. According to the coordinate of the route, the mean sea level data of DTU10 model was got. Compared the smoothed GPS elevation with the model data, the calculated tide was obtained. Comparative analysis was performed between calculated tide and forecast tide. The dif-ference is-0.11 m, and it could meet the requirement of bathymetry of 200 m areas.关键词
