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 )
主要研究內容包括:一、總結分析了當前水下導航的常用方法和不足之處,指出基於航位推算的導航方法,存在著最大的問題就是導航誤差的積累問題,如果沒有修正系統,這種方法很難滿足使用要求;其次指出基於聲學的導航方法,造價昂貴,導航范圍有限,難以滿足自主水下航行器大范圍導航的需求;二、總結了當前水下地形輔助導航的主要技術路線,一是基於地形高程的匹配方法,這是當前研究的重點;二是基於地形圖像的匹配方法,由於缺乏良好的圖像傳感器,和可用的海底圖像地圖,目前這種方法還有待研究發展;三、將兩種地形高程匹配的常用方法應用到自主水下航行器上:以相關演算法為前提的地形輪廓匹配( tercom )方法和以卡爾曼濾波為基礎的桑迪亞慣性地形輔助導航( sitan )方法,前者演算法簡單可靠,但是導航精度不高,後者雖然精度比較高,但存在著演算法較為復雜、有可能發散和出現奇異值等問題。Abstract : compared the accuracy of the digital terain models enlarged form the air photographs kept in stock, pointed out the reliability and frugality of the computerizing optimum choosing route in surveying and designing the expressway, and proved the feasibility of choosing the optimum route by taking two steps and the effect it has on the investment of the expressway construction and the policy - making as well
