摘要
大型船舶运动性能的测定,采用传统的测速区测速法因受海域水深及环境因素的制约,往往难以实施。船载GPS具有定位精度高的特点,此文给出了利用GPS在宽阔海域测定船舶航速和计程仪改正率的方法及测速精度分析,可供大型船舶测定船舶运动性能时应用。
Against the issue of ship motion performance measurement, based on the traditional speed zone speed measurement method, by using ship-borne high-precision GPS, it presents the principle, realization and accuracy analysis of measuring the ship＇s speed and percentage of log correction by using GPS, and the method works simple, economic and practical.
