【摘要】 关于优化船体导航的快速性,在船姿态测量问题的研究中,现有导航GPS对船体姿态测量运算量大,动态实时性差的特点。为解决上述问题,提出先建立卫星与基线间的空间基本模型,然后将基本模型在实际应用框架中进行讨论,在充分利用其几何关系传递与三角函数运算后,将二元非线性方程组化简为类一元高阶方程的形式,然后结合计算机对一元高阶方程求解的快速捕捉能力,以最短的时间获得方程组的函数解,而后确定对姿态求解。解决了以往无法直接求取解析解的难题,使方程的转化与计算机处理有机结合在一起。仿真结果表明,在同样精度要求下方法更快速、有效。更多还原

【Abstract】 This paper studied GPS attitude determination.For existing GPS attitude determination algorithm has the characteristics of large computing and poor dynamic real-time,the paper first established the basic space model between satellite and baseline,then applicated the basic model in the framework of the discussion.In the full use of its geometry transfer and computing trigonometric functions,binary nonlinear equations were put into a simplified form of higher order equation.And then,computer was used for higher order equations in shortest possible time to obtain solutions and then determine the attitude solution.Simulation results show that to meet the same accuracy requirement,the method is more rapid and effective.更多还原
