A method has been developed to calibrate the positions of the transducer and the transponder in the ultra - short baseline acoustic position system ( usbl ) 摘要提出了超短基線水聲定位系統( usbl )的校準方法,并用模擬數據進行了驗證。
Surely , the inertial navigation has high precision , but it is also costly . acoustic tracking location is not a good way for voyage a long distance 慣性導航系統精度高,但設備昂貴,水聲定位系統不適合機器人長航時的導航定位。
Usually , there are three available accesses for location underwater , inertial navigation , dead reckoning navigation , acoustic tracking location 從目前來看,應用于水下導航的方法主要有:慣性導航、船位推算導航、水聲定位系統等方法。
Acoustic positioning system has wide application in ocean scientific field . however , existing systems have disadvantages of bulkiness , perplexing operation , limited position range and low precision , resulting in their incompetence of satisfying many application needs 水聲定位系統在海洋科學領域應用廣泛,但原有系統大多或設備龐大、操作復雜,或定位范圍小、精度低,很難真正下滿足使用需求。
Firstly , the basic theory of the ultra - short baseline system is dissertated . and then , several typical localization model of four cell lineup is analyzed and investigated thoroughly . a optimal localization model is educed by contrasting performance and analyzing precision 首先論述了現有超短基線被動聲定位系統的基本理論,緊接著深入研究了幾種典型的四元方陣的定位模型,通過性能對比、精度分析,討論得出了最優的定位模型。
