Application of ultrashort baseline positioning system and acoustic doppler current profiler in underwater archaeology of the shipwreck by Shengbeiyu Island
This paper introduced the working principles and application scenarios of ultra short baseline positioning system and acoustic Doppler current profiler.According to the underwater archaeological work requirements of the Shengbeiyu Island shipwreck in Zhangzhou,two types of equipment were comprehensively used to carry out real-time data collection and analysis,obtaining high-precision underwater absolute position information and accurate tidal hydrological observation data such as flow velocity direction,thereby improving the accuracy of site positioning.A real-time monitoring system for the entire site's ocean current profile was established,and an innovative underwater archaeological real-time positioning and monitoring system was developed to ensure the safety of underwater archaeological operations and provide technical support for shipwreck archaeological excavation work.By improving the anti-interference design of the ultra short baseline system,the stability and reliability of the system in the environment have been enhanced to address issues such as location jumps in work.
