摘　　要：利用无人船无验潮测深与网络RTK技术开展内河水深测量试验,并从测深精度、路径跟踪及最大抗水流能力三个方面评估该自主研发无人船性能。结果表明,无人船水深测量精度高,满足相关规范要求,且无人船在水流速<2.0 m/s条件下,抗水流速能力强,路径跟踪精度良好,外业作业最大抗水流速安全阈值为5.0 m/s。Unmanned vessel non-tide depth measurement and network RTK technology were used to conduct water depth measurement experiments in inland rivers,based on which the performance of the independently developed unmanned vessel was evaluated from three aspects of depth measurement accuracy,path tracking and the maximum resistance to water flow.The results show that the unmanned vessel has high accuracy in water depth measurement,meets the requirements of relevant specifications,and has strong resistance to water flow and good path tracking ac⁃curacy under the condition of water flow velocity less than 2.0 m/s.The maximum safety threshold of water flow ve⁃locity for field operations is 5.0 m/s.
