例句与用法
- Celestial navigation has many advantages in this field because of its completely autonomous ability and high resulted navigation accuracy
天文导航具有完全自主、导航误差不随时间累积的优点。 - On the other hand , inertial navigation must be integrated with extraneous information feedback to form a stable and closed - form integrated navigation system , so as to limit the error accumulation
另一方面,惯性导航必须引入外部信息反馈,形成稳定的闭环的组合导航系统,以抑制惯性导航误差的发散。 - Secondly , it provides some arithmetic and positioning methods used in the network - based navigation system and simulation outcomes . then , the paper analyses some errors of network - based navigation system . it studies error propagation of relay positioning and gives simulation results
然后给出了网络化导航的定位方法和算法,并结合具体算法进行了定位仿真计算;接着对网络化导航误差进行了分析,研究了接力定位的误差传递情况并进行了仿真和结果分析。 - In this paper , the main research works are as follows : 1 ) survey and analysis previous work in auv navigation and summarize : as the cumulate error , the dead - reckoning and inertial navigation systems ca n ' t be used without other modified system ; the acoustic navigation system is used only in small range , and is very expensive . 2 ) two important approaches in geophysical navigation techniques are summarized , one is terrain contour based navigation , this approach is investigated keystone today ; the other is image based navigation , due to no perfect image sensors and image seabed map , this approach has seldom been practised . 3 ) two important terrain contour based navigation algorithms has been applied to auv , one is match algorithm - based terrain contour match ( tercom ) ; the other is kalman filter - based sandia inertia terrain - aided navigation ( sitan )
主要研究内容包括:一、总结分析了当前水下导航的常用方法和不足之处,指出基于航位推算的导航方法,存在着最大的问题就是导航误差的积累问题,如果没有修正系统,这种方法很难满足使用要求;其次指出基于声学的导航方法,造价昂贵,导航范围有限,难以满足自主水下航行器大范围导航的需求;二、总结了当前水下地形辅助导航的主要技术路线,一是基于地形高程的匹配方法,这是当前研究的重点;二是基于地形图像的匹配方法,由于缺乏良好的图像传感器,和可用的海底图像地图,目前这种方法还有待研究发展;三、将两种地形高程匹配的常用方法应用到自主水下航行器上:以相关算法为前提的地形轮廓匹配( tercom )方法和以卡尔曼滤波为基础的桑迪亚惯性地形辅助导航( sitan )方法,前者算法简单可靠,但是导航精度不高,后者虽然精度比较高,但存在着算法较为复杂、有可能发散和出现奇异值等问题。 - Different sampling periods of sensors and the recursive steps of initial states are investigated . the navigation precision with different condition such as different precision of sensors , different length of observation time are compared . then , three orbit types , consisting of low - altitude orbit , middle - altitude orbit and high - altitude orbit , are simulated respectively
在pc机上首先分析敏感器采样周期和滤波迭代次数对自主导航精度的影响,然后比较敏感器精度不同,观测时间长短不同,轨道类型不同情况下所产生的导航误差。
