测站调查中设备的定位是海洋地质调查的一项重要技术,调查设备的位置信息是作业过程中的重要参考,传统的船舶定位精度较差,尤其在较深的海域和复杂的海况下定位精度下降更为明显,而水下定位系统可弥补传统定位的不足。文章首先介绍了传统船舶定位和USBL定位的工作方法,然后分析了同等作业环境下两种方法的定位精度,通过对比分析得出船舶定位法在较差的作业环境下误差较大,不能完全满足作业需求,而USBL定位的精度和可靠性较高,本着科学研究的严谨性,应在海洋地质调查中得到更为广泛的应用。
The location of equipment in survey station is an important technique of marine geological survey. The location information of survey equipment is an important reference in the operation process. The traditional ship positioning accuracy is poor, especially in the deep sea area and complex sea conditions The accuracy is more obvious decline, and underwater positioning system can make up for the lack of traditional positioning. The article first introduces the working method of traditional ship positioning and USBL positioning, and then analyzes the positioning accuracy of the two methods in the same working environment. Through comparative analysis, it is concluded that the ship positioning method has larger error in poor working environment and can not fully meet However, the accuracy and reliability of USBL positioning are higher. In the rigor of scientific research, it should be more widely used in marine geological surveys.
