摘要
对基于GPS-OEM板开发的传统航海导航软件进行了深入研究.找出了影响导航精度的主要因素,并针对这几种因素分别提出了相应的解决方案.针对定位误差,采用卡尔曼滤波方法处理航行体位置信息,建立了卡尔曼动态滤波模型.针对航行体速度误差,采用曲线拟合航程方法进行航行体速度平滑.当GPS定位信息无效时,给出船位推算模型来推算航行体位置.
Traditional marine navigation software based on GPS-OEM board is studied.Main factors affecting navigation accuracy are found,and the corresponding solutions are presented.The conversion methods among different preference frames are analyzed to solve reference frame error,and mathematic models are set.Normal and improved Kalman filter models are used to process position coordinates flatness because there is position error.When position data is invalid,the model of position calcaulation is considered.
