摘要

意大利核物理研究所(INFN)正在制造一套同步声信标,它将被放置在3000米深的水中,以定位大量的光学模块。该技术演示器位于卡塔尼亚近海。在最后的配置中,未来的探测器将占据一个所有维度都为1公里的立方体。该系统由多达5个海底同步信标和安装在压力外壳内的一些声学数字接收器组成,将提供亚米级精度。该系统将于2005年交付。对于这种应用,INFN合作伙伴ACSA水下GPS将引入一种称为时谱扩展码(TSSC)的新技术。报告将涵盖水下定位技术:系统架构,技术和先进的数据处理方面。

Scientific application of advanced underwater positioning techniques
The Italian Institute For Nuclear Physics, INFN, has under manufacturing a set of synchronous acoustic beacons that will be laid in 3000 m of water depth to position a large number of optical modules. The technology demonstrator is located offshore Catania. In the final configuration, future detectors will be occupying a cube having one kilometre in all dimensions. The system composed of up to 5 seabed synchronous beacons and a number of acoustic digital receivers mounted inside the pressure housings will offer a sub-metric accuracy. Delivery of the system will take place in 2005. For this application, ACSA Underwater GPS, INFN partner, will introduce a new technology known as Time Spectral Spread Codes, "TSSC". The presentation will cover underwater positioning techniques: system architecture, technical and advanced data processing aspects.
