Another vital technology is the chikyu ' s dynamic positioning system , an automatic , satellite - guided location fixer that corrects against wind , wave and current forces with six 360 - degree thrusters under the hull , keeping the ship over the borehole 地球號另一個重要的技術則是動態定位系統,這是一個利用衛星導航的自動定位器,并且校正了風速、海浪與船底的六個360度推進器產生的力量,使船可以一直維持在鉆孔的上方。
At the basis of designing underwater geomorphological measurement system concrete plan , this dissertation makes study and analysis on its measuring depth of water sonar system and dynamic global position system . this dissertation simply and thoroughly introduces the state of underwater acoustic transducer and array . it covers the basic situation , the study benefits , the classification and role , analyses the performance index , designs the performance parameter relating to themselves performance synthesis and sonar equation 論文在制定水下地貌測量系統技術方案的基礎上,論述了該系統中的水深測量聲納系統和動態定位系統( dgps ) ,分析了水聲換能器及基陣的性能指標,確定了換能器及基陣的主要性能參數。
