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
