国产尾标定位系统的研究及应用

The research and application of domestic tail positioning system

对中国石油大学自主研发的全球卫星导航系统(GNSS)尾标定位系统的组成及运行原理进行了详细的阐述.介绍了该尾标定位系统在海洋拖缆作业中的应用,包括其核心软硬件的设计和主要工作流程.通过陆上模拟实验,对其电台传输距离和稳定性及定位精度进行测试,测试结果表明,尾标定位系统能够连续稳定地传输数据且能够实现厘米级的相对定位精度,可以满足实际生产中海上拖缆作业对导航定位的需求.

The composition and operation principle of the tail mark positioning system of GNSS independently developed by China University of Petroleum are described in detail.Then it introduces the application of self-developed tail positioning system in marine streamer operation,which including design of its core hardware and software and main workflow.Finally,the radio transmission distance and stability and positioning accuracy are tested by land-based simulation experiments.The test results show that the tail positioning system can continuously and stably transmit data and can achieve centimeter-level relative positioning accuracy,which can meet the requirements of navigation and positioning for offshore towing cable operation in actual production.
