This paper proposes a fusion positioning method that can achieve stable and no hop points by adjusting parameters and predicting trends, even with a one-sided lack of fusion data. The method combines acoustic signal and\n            <jats:bold>Inertial Measurement Unit (IMU)<\/jats:bold>\n            data, exploiting their respective advantages. The fusion is achieved using the Kalman filter and Bayesian parameter estimation is performed for tuning IMU parameters and predicting motion trends. The proposed method overcomes the problem of fusion failure caused by long-term unilateral data loss in traditional fusion positioning. The positioning trajectory and error distribution analysis show that the proposed method performs optimally in severe NLoS experiments.\n          <\/jats:p>","DOI":"10.1145\/3589765","type":"journal-article","created":{"date-parts":[[2023,4,13]],"date-time":"2023-04-13T12:38:33Z","timestamp":1681389513000},"page":"1-19","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["A Highly Stable Fusion Positioning System of Smartphone under NLoS Acoustic Indoor Environment"],"prefix":"10.1145","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9744-389X","authenticated-orcid":false,"given":"Hucheng","family":"Wang","sequence":"first","affiliation":[{"name":"Guilin University of Electronic Technology, Zhejiang University"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0490-2031","authenticated-orcid":false,"given":"Zhi","family":"Wang","sequence":"additional","affiliation":[{"name":"Zhejiang University"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5879-514X","authenticated-orcid":false,"given":"Lei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Chang\u2019an University"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0751-5045","authenticated-orcid":false,"given":"Xiaonan","family":"Luo","sequence":"additional","affiliation":[{"name":"Guilin University of Electronic Technology"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8771-8901","authenticated-orcid":false,"given":"Xinheng","family":"Wang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Jiaotong-Liverpool University"}]}],"member":"320","published-online":{"date-parts":[[2023,5,19]]},"reference":[{"key":"e_1_3_1_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2015.2478451"},{"key":"e_1_3_1_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2020.2992341"},{"key":"e_1_3_1_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2020.2993052"},{"key":"e_1_3_1_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2018.2839112"},{"key":"e_1_3_1_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2022.3149048"},{"key":"e_1_3_1_7_1","doi-asserted-by":"crossref","first-page":"1029","DOI":"10.1109\/PLANS46316.2020.9110232","volume-title":"2020 IEEE\/ION Position, Location and Navigation Symposium (PLANS\u201920)","author":"Gentner Christian","year":"2020","unstructured":"Christian Gentner, Markus Ulmschneider, Isabel Kuehner, and Armin Dammann. 2020.
