However, they present several logistical constraints including receiver maintenance, calibration procedures and limited access to real-time data. We present here a novel, easy-to-deploy, energy self-sufficient underwater positioning system based on the time difference of arrival (TDOA) algorithm and the Global System for Mobile (GSM) communication technology, capable of locating tagged marine organisms in real time. We provide an illustration of the application of this system with empirical examples using continuous and coded tags in fish and benthic invertebrates. In situ experimental tests of the operational system demonstrated similar performances to currently available acoustic positioning systems, with a global positioning error of 7.13 \u00b1 5.80 m (mean \u00b1 SD) and one-third of the pings can be localized within 278 m of the farthest buoy. Despite some required improvements, this prototype is designed to be autonomous and can be deployed from the surface in various environments (rivers, lakes, and oceans). It was proven to be useful to monitor a wide variety of species (benthic and pelagic) in real time. Its real-time property can be used to rapidly detect system failure, optimize deployment design, or for ecological or conservation applications.<\/jats:p>","DOI":"10.3390\/s22218208","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T09:59:37Z","timestamp":1666778377000},"page":"8208","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Wireless Autonomous Real-Time Underwater Acoustic Positioning System"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1569-583X","authenticated-orcid":false,"given":"Fran\u00e7ois-Marie","family":"Manicacci","sequence":"first","affiliation":[{"name":"UMS 3514 Plateforme Marine Stella Mare, Universit\u00e9 de Corse Pasquale Paoli, 20620 Biguglia, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9019-1717","authenticated-orcid":false,"given":"Johann","family":"Mourier","sequence":"additional","affiliation":[{"name":"UMS 3514 Plateforme Marine Stella Mare, Universit\u00e9 de Corse Pasquale Paoli, 20620 Biguglia, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3718-9447","authenticated-orcid":false,"given":"Chabi","family":"Babatounde","sequence":"additional","affiliation":[{"name":"UMS 3514 Plateforme Marine Stella Mare, Universit\u00e9 de Corse Pasquale Paoli, 20620 Biguglia, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jessica","family":"Garcia","sequence":"additional","affiliation":[{"name":"UMS 3514 Plateforme Marine Stella Mare, Universit\u00e9 de Corse Pasquale Paoli, 20620 Biguglia, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Micka\u00ebl","family":"Broutta","sequence":"additional","affiliation":[{"name":"UMS 3514 Plateforme Marine Stella Mare, Universit\u00e9 de Corse Pasquale Paoli, 20620 Biguglia, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-S\u00e9bastien","family":"Gualtieri","sequence":"additional","affiliation":[{"name":"Soci\u00e9t\u00e9 Informatique et Technologique Corse (S.I.T.E.C), Parc Technologique d\u2019Erbajolo, 20601 Furiani, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5930-0302","authenticated-orcid":false,"given":"Antoine","family":"Aiello","sequence":"additional","affiliation":[{"name":"UMS 3514 Plateforme Marine Stella Mare, Universit\u00e9 de Corse Pasquale Paoli, 20620 Biguglia, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6240","DOI":"10.1126\/science.1255642","article-title":"Aquatic animal telemetry: A panoramic window into the underwater world","volume":"348","author":"Hussey","year":"2015","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"884","DOI":"10.1093\/biosci\/bix098","article-title":"Envisioning the future of aquatic animal tracking: Technology, science, and application","volume":"67","author":"Lennox","year":"2017","journal-title":"BioScience"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"364","DOI":"10.1016\/j.fishres.2011.01.011","article-title":"Testing a new acoustic telemetry technique to quantify long-term, fine-scale movements of aquatic animals","volume":"108","author":"Espinoza","year":"2011","journal-title":"Fish.
