船用捷联系统姿态算法的仿真研究

Simulation and Research on Attitude Algorism of the Strapdown Inertial System Used on Ship

随着惯性器件的质量日益提高和计算机技术的飞速发展,惯性捷联系统已从航天、航空向航海领域延伸。本文主要研究在舰船运动环境下捷联系统的姿态算法,并以典型船舶运动为实例对五种不同的算法进行了计算机实时仿真和比较,所得结论,将对研制船用捷联系统具有参考意义。

Along with the unceasing perfect of the qualities of the inertial sensors and the quickly developing of Computer technology,the application of the strapdown inertial navigation system has extended from the area of aviation and spaceflight to ship's navigation.In this paper the attitude algorism of the strapdown inertial system in the condition of ship's motion has been researched mainly,using computer to simulate the performance of the strapdown system under the typical motion of ship on the sea,the five types of attitude algorism have been discussed and their merits and demerits also have been compared.The conclusions,got in this pa- per,will be meaning for reference.
