面向OBS布设与定位回收的船舶导航系统研究
|
摘要
针对海洋勘探中对OBS精确布阵的要求,综合利用USBL水下定位技术、DGPS定位技术、GIS技术以及网络通信技术,研究专业面向OBS布设、精确定位与回收的船舶导航系统。介绍了系统的结构和功能,分析了系统的主要特点,并探讨了该系统的关键技术。目前该系统已应用于生产实践,实践表明:系统能够有效提高OBS布设、定位的精度和效率。
For the requirements of accurate embattled OBS in the marine survey and exploration,an analysis of Marine Navigation System which serves OBS deployment,accurate positioning and retrievement was made by making use of the USBL underwater positioning technology,DGPS technology,GIS technology and network communication technology,and the structure and function of the system was introduced,and the main characteristic was analyzed,and the key technology was studied.The system has been used for production,practices show that the system could effectively improve the accuracy and efficiency of OBS emplaced and positioned.
