摘要
通过对组成舰船GPS导航系统定位误差的估计和船舶准确位置的计算,建立了舰船GPS导航系统(Global Positioning System)定位信号仿真模型。特别是针对船舶航行时的不同海况和天气条件,给GPS定位误差估计引入了影响因子后,使舰船GPS导航系统定位误差信号仿真更加精确和可靠。
It is presented the GPS signal simulation model of marine navigational systems. Through calculating the accurate situation of marine and through estimating the GPS situation error, especially the error factor according to different states of the sea and weather, the model becomes more accurate and reliable than before.
