| 摘 要： | 提出了利用数据融合技术来提高测量船的导航系统精度的方法.针对测量船上的惯性导航系统在长时间运行后产生误差的问题,通过测量船上的天文经纬仪观测恒星,利用卡尔曼滤波把惯性导航、天文导航等其他导航系统组成组合导航系统,并建立了数学模型.同时在卡尔曼滤波中引入模糊控制理论,来解决所建立的数学模型中量测噪声不满足零均值高斯白噪声的问题.实验结果与理论分析一致,证明利用多种数据融合方法能有效提高测量船导航系统的精度.

| Abstract: | This paper presents a method to heighten measurement ship's navigation accuracy using data fusion theory.Kalman filter is used to fuse data from INS,CNS and other navigation systems by observing stars with celestial theodolite in measurement ship and combined navigation is build.Fuzzy control is combined with Kalman filter to resolve problem that measurement noise in Kalman filter model is not a zero-mean,white noise with a Gaussian distribution.Experiment results coincide with theoretical analysis,it shows that several kinds of data fusion methods can improve measurement ship's navigation accuracy effectively. |
