navigation error meaning in English
导航设施
导航误差
Examples
- Some teams may cover twice the distance due to their route and navigation errors
有的队由于路线及识图越野出现偏差，可能要走两倍于直线距离的路程。 - And in the early time many integrated navigation error model was come into being . in all of them the model derivated by britting and widnall was the representative
最具代表性的是利用britting和widnall推导出的误差模型,该模型是基于地理系,考虑到系统误差和传感器误差。 - After the instrument error of sins is analyzed , it can be concluded that the quadratic model is more sensible to navigation error , and with instrument error taken into account , the linear model is better than the quadratic model
通过捷联惯导仪器误差的分析，发现二次模型对捷联惯导导航参数误差更为敏感，考虑惯导仪器误差后，线性模型的修正效果要优于二次模型。 - The paper presents the form of sins / odometer ( od ) / global position system ( gps ) integrated navigation system based on sins . state and observation equations are established for kalman filter . the simulation result shows that the integrated navigation system can reduce navigation error when using the feedback calibration method
对捷联惯导系统、里程仪( od )和全球定位系统( gps )误差方程进行了分析，建立了以捷联惯导系统为主的用于卡尔曼滤波的系统方程和观测方程，给出了车载组合导航系统的分布式滤波组合方案。 - Abstract : the attitude error performance of electrostatic gyro should be understood and the relevant error equations must be set up in order to ensure the navigation precision of esgm . the relation between the navigation errors and the attitude errors of gyro was derived by use of spherical triangle . the simulation results show that the temporal performances of the longitudinal and distance errors which come from the initial alignment errors are periodically variational . they also show that the longitudinal and distance errors resulted from gyro drifts are not convergent in time . thus , the effects of initial alignment errors and gyro drifts can not be neglected and must be estimated and compensated
文摘:为了保证静电监控器的导航定位精度，需要了解静电陀螺的姿态误差特性，建立相应的误差方程.本文采用球面三角形原理推导了导航定位误差与陀螺姿态误差的关系式.仿真结果表明，由初始定向误差引起的经度误差和距离误差的时间特性是周期变化的；由陀螺漂移引起的经度误差和距离误差是随时间发散的.因此，初始定向误差和陀螺漂移的影响不能忽略，必须对其进行估计和补偿
