摘 要：“深水高精度水下綜合定位系統(tǒng)”課題目標(biāo)旨在緊密結(jié)合載人潛器及其它深海水下探測和作業(yè)的技術(shù)需求，研制一套具有自主知識(shí)產(chǎn)權(quán)水下綜合定位系統(tǒng)的工程化樣機(jī)，可以在深度剖面內(nèi)提供高精度定位服務(wù)，初步形成國產(chǎn)水下綜合定位系統(tǒng)產(chǎn)業(yè)化條件，為我國深?？茖W(xué)考察、海洋資源勘探開發(fā)、深海工作站建設(shè)、海洋工程建設(shè)等提供高精度定位支持。課題具體包括綜合定位系統(tǒng)原理樣機(jī)研制與驗(yàn)證、綜合定位系統(tǒng)定型樣機(jī)研制與工藝設(shè)計(jì)，系統(tǒng)與船的總體集成和試驗(yàn)檢驗(yàn)三個(gè)部分，并包含換能器7 000 m耐壓、陣型自校準(zhǔn)、超短基線/長基線定位融合和水下AUV自主定位與狀態(tài)監(jiān)控等多項(xiàng)關(guān)鍵技術(shù)的研究。報(bào)告基于課題研究背景和基礎(chǔ)，匯報(bào)了課題的主要研究內(nèi)容情況和總體方案以及研制進(jìn)度與成果。目前已完成了系統(tǒng)詳細(xì)設(shè)計(jì)方案、原理樣機(jī)的研制以及原理樣機(jī)的湖試海試，系統(tǒng)定型樣機(jī)正在設(shè)計(jì)研制當(dāng)中。經(jīng)過實(shí)驗(yàn)室測試聯(lián)調(diào)，湖上試驗(yàn)和海試試驗(yàn)，超短基線定位部分已取得了大量成果，定位精度、作用距離得到了實(shí)際應(yīng)用的驗(yàn)證，系統(tǒng)軟硬件湖、海試驗(yàn)過程中具備良好的穩(wěn)定性。另一方面，借助英國和法國長基線定位系統(tǒng)的試驗(yàn)，梯隊(duì)積累了更多的經(jīng)驗(yàn)知識(shí)，為綜合定位系統(tǒng)的研制提供了有力的借鑒。AUV自主定位單元已完成詳細(xì)設(shè)計(jì)，正在有序的開發(fā)調(diào)試，為下一步的集成做準(zhǔn)備。

Abstract：Deep Sea High Precision Underwater LUSBL Positioning System Project is aimed to develop a LUSBL positioning system with self intellectual property rights to satisfy the technical demand of HOV/AUV/ROV operation and observation.By this project，on one hand industrialization will be primarily formed.On the other hand，ocean engineering，deep sea resource observation and ocean scientific research will also be well supported.Principle model development，final model development，ship installation and trial test are the main component of the project.Key technologies include 7 000 m transducer，array self-calibration，LBL/USBL data fusion and AUV positioning methods.Based on project background，research content，total precept and research progress are reported.Till now，detail design，principle model development and lake/sea trial have been accomplished.USBL system has obtained quantities of trial results by which its positioning precision，operating distance，system stability are well tested.Moreover， our group learned much by British and French LBL system.It will be definitely helpful for our LUSBL system development.AUV positioning module was designed in detail.Now it is under debugging and will soon be ready for system integration.

Key Words：LUSBL system；Deep sea；High precision
