水聲定位系統(tǒng)——固定式定位跟*系統(tǒng)的水下測量設備大多數(shù)固定在海底，其范圍大、費用高，只能在固定海區(qū)使用；活動式定位跟*系統(tǒng)的全部設備都固定安裝在活動平臺上，試驗時隨活動平臺開往試驗海區(qū)；輕便式定位跟*系統(tǒng)的體積和重量相對較小，可以隨時布放和回收，并可通過飛機、車輛和船只從一個試驗區(qū)運送到另一個試驗區(qū)。這三種水下定位定位跟*系統(tǒng)雖然在結構上有較大差別，但在原理上均是依賴于幾何原理的水聲學定位方法。根據(jù)接收基陣的基線可以將水聲定位技術分為三類：長基線(LongBase-Line)、短基線(ShortBase-Line)、超短基線(UltraShortBase-Line)。四川水下小目標識別裝備聲學多普勒速度儀裝備生產(chǎn)公司。</p><div

聲學導航定位：水聲導航是在聲納和無線電導航的綜合技術基礎上發(fā)展起來的導航技術。水聲定位系統(tǒng)具有多個基元，基元一般為接收儀器或應答器，基元間連線稱為基線，根據(jù)基線長度可分<span

海底地震儀分為單分量和三分量兩種。單分量地震儀記錄垂直分量,頻率范圍為2～20赫，動態(tài)范圍可達65分貝,石英鐘精度為10-6秒，功率為0.5瓦/小時，記錄時間為30天。三分量(兩個水平分量和一個垂直分量)地震儀，一般是由三個方向安置的單分量地震儀和一個水聽器組成,前者在海底直接測量地震波的縱波和橫波,后者測量水中傳播的地震波（縱波）。蘇聯(lián)、美國、英國、日本等進行了海底地震儀的研制和觀測方法的試驗，并在不同海底區(qū)，如大洋洋脊、島弧、海溝、深海洋盆等地區(qū)，利用海底地震儀進行過觀測，發(fā)現(xiàn)洋脊區(qū)的微地震活動規(guī)律和海溝區(qū)震源深度的分布特征（見海底地震）。多普勒計程儀裝備生產(chǎn)公司。</p><div

水下導航定位，慣性導航：慣性導航是一種自主式的導航方法。它完全依靠機載設備自主的完成導航任務，和外界不發(fā)生任何光、電聯(lián)系，因此隱蔽性好，工作不受氣候條件的限制。這一獨特的優(yōu)點，對作為軍*目的而應用的各種航行器特別重要。所以近幾十年來，慣性導航在導彈、艦船、潛艇、水下武器、飛機、宇宙航行器上都得到了寬泛的應用，在導航技術中占有突出的地位。慣性導航用于水下導航，是通過將加速度對時間兩次積分來獲得水下潛器的位置，其優(yōu)點是自主性和隱蔽性好。缺點是由于陀螺隨時間不斷漂移，在長時間工作情況下導航定位累積誤差較大。早期的慣導系統(tǒng)復雜、體積大、能耗高不適合潛水器使用，現(xiàn)在隨著光纖、激光等新型固態(tài)陀螺技術的不斷進步，為實現(xiàn)研制體積小、精度高、可靠性好、能耗與成本指標低的INS提供了條件，因此在未來的自主式潛航器（AUV)上將有可能大量采用這些新型INS。目前，國外水下潛器常用的INS主要有:美國霍尼韋爾公司RL34環(huán)形激光陀螺慣性導航系統(tǒng)、美國Crossbow公司的微機械陀螺慣性導航系統(tǒng)等。四川水下無線對講設備</p><p
