By utilizing variables such as acceleration, angle, angular velocity, and propeller speed as inputs, the Self-Attention mechanism is constructed using Long Short-Term Memory (LSTM) for handling the above information, enhancing the model\u2019s accuracy during persistent bottom-track velocity failures. Additionally, this study introduces the water-track velocity information to enhance the generalization capability of the network and improve its speed estimation accuracy. The sea trial experiment results indicate that compared to traditional methods, this model demonstrates higher accuracy and reliability with both position error and velocity error analysis when the used Pathfinder DVL fails, providing an effective solution for AUV combined navigation systems.<\/jats:p>","DOI":"10.3390\/rs16142580","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T12:44:36Z","timestamp":1721047476000},"page":"2580","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cruise Speed Model Based on Self-Attention Mechanism for Autonomous Underwater Vehicle Navigation"],"prefix":"10.3390","volume":"16","author":[{"given":"Xiaokai","family":"Mu","sequence":"first","affiliation":[{"name":"Key Laboratory of Autonomous Marine Vehicle Technology, Harbin Engineering University, Harbin 150001, China"},{"name":"Qingdao Innovation and Development Center, Harbin Engineering University, Qingdao 266000, China"}]},{"given":"Yuanhang","family":"Yi","sequence":"additional","affiliation":[{"name":"Qingdao Innovation and Development Base, Harbin Engineering University, Qingdao 266000, China"}]},{"given":"Zhongben","family":"Zhu","sequence":"additional","affiliation":[{"name":"Qingdao Innovation and Development Base, Harbin Engineering University, Qingdao 266000, China"}]},{"given":"Lili","family":"Zhu","sequence":"additional","affiliation":[{"name":"Qingdao Innovation and Development Base, Harbin Engineering University, Qingdao 266000, China"}]},{"given":"Zhuo","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Autonomous Marine Vehicle Technology, Harbin Engineering University, Harbin 150001, China"}]},{"given":"Hongde","family":"Qin","sequence":"additional","affiliation":[{"name":"Key Laboratory of Autonomous Marine Vehicle Technology, Harbin Engineering University, Harbin 150001, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"238","DOI":"10.1631\/jzus.A2200621","article-title":"Development of underwater electric manipulator based on interventional autonomous underwater vehicle (AUV)","volume":"25","author":"Hu","year":"2024","journal-title":"J.
