This study proposes a method establishing a four-dimensional evaluation framework for the USBL (Ultra-Short Baseline) positioning system. The framework encompasses signal quality, geometric precision, environmental attenuation, and data stability. It enables the quantitative, real-time assessment of system reliability. Consequently, it facilitates an adaptive weight adjustment mechanism. Experimental results demonstrate that under harsh conditions featuring jump point anomalies and data loss, the proposed algorithm achieves an average position error of 1.15 m. This represents a 53.1% improvement over conventional methods, with the enhancement reaching 58.9% in scenarios specifically affected by jump points. The proposed method study effectively enhances the navigation reliability of manned submersibles in complex underwater acoustic environments, thereby demonstrating significant engineering application value.<\/jats:p>","DOI":"10.3390\/s26041359","type":"journal-article","created":{"date-parts":[[2026,2,20]],"date-time":"2026-02-20T15:57:11Z","timestamp":1771603031000},"page":"1359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Multi-Source Confidence Assessment-Based Adaptive Calibration for Deep-Sea Manned Submersible Integrated Navigation"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-7208-5904","authenticated-orcid":false,"given":"Yixu","family":"Liu","sequence":"first","affiliation":[{"name":"National Deep Sea Center, Qingdao 266237, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wentao","family":"Fu","sequence":"additional","affiliation":[{"name":"National Deep Sea Center, Qingdao 266237, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengya","family":"Zhao","sequence":"additional","affiliation":[{"name":"National Deep Sea Center, Qingdao 266237, China"},{"name":"College of Intelligent Systems Science and Engineering, Harbin Engineering University, Harbin 150006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongfu","family":"Sun","sequence":"additional","affiliation":[{"name":"National Deep Sea Center, Qingdao 266237, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,20]]},"reference":[{"key":"ref_1","first-page":"38","article-title":"Current progress and future development trends of deep-sea exploration technology","volume":"43","author":"Cui","year":"2025","journal-title":"Sci.
