In this paper, we compare and analyze two prominent solutions based on Ultra Wide Band Radio (Pozyx) and Ultrasound (GoT), both installed in an industrial manufacturing laboratory. The comparison comprises a static and a dynamic case. The static case evaluates average localization errors over 90 s intervals for 100 ground-truth points at three different heights, corresponding to different relevant objects in an industrial environment: mobile robots, pallets, forklifts and worker helmets. The average error obtained across the laboratory is similar for both systems and is between 0.3 m and 0.6 m, with higher errors for low altitudes. The dynamic case is performed with a mobile robot travelling with an average speed of 0.5 m\/s at a height of 0.3 m. In this case, low frequency error components are filtered out to focus the comparison on dynamic errors. Average dynamic errors are within 0.3\u20130.4 m for Pozyx and within 0.1\u20130.2 m for GoT. Results show an acceptable accuracy required for tracking people or objects and could serve as a guideline for the least achievable accuracy when applied for mobile robotics in conjunction with other elements of a robotic navigation stack.<\/jats:p>","DOI":"10.3390\/s22082927","type":"journal-article","created":{"date-parts":[[2022,4,12]],"date-time":"2022-04-12T22:48:45Z","timestamp":1649803725000},"page":"2927","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Evaluation and Comparison of Ultrasonic and UWB Technology for Indoor Localization in an Industrial Environment"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0838-3870","authenticated-orcid":false,"given":"Amalia Lelia","family":"Cre\u021bu-S\u00eercu","sequence":"first","affiliation":[{"name":"Department for Materials and Production, Aalborg University, 9220 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7288-7638","authenticated-orcid":false,"given":"Henrik","family":"Schi\u00f8ler","sequence":"additional","affiliation":[{"name":"Department for Electronic Systems, Aalborg University, 9220 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2249-7877","authenticated-orcid":false,"given":"Jens Peter","family":"Cederholm","sequence":"additional","affiliation":[{"name":"Department for Planning, Aalborg University, 9000 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ion","family":"S\u00eercu","sequence":"additional","affiliation":[{"name":"Department for Materials and Production, Aalborg University, 9220 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1623-6080","authenticated-orcid":false,"given":"Allan","family":"Schj\u00f8rring","sequence":"additional","affiliation":[{"name":"Department for Electronic Systems, Aalborg University, 9220 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9258-4194","authenticated-orcid":false,"given":"Ignacio Rodriguez","family":"Larrad","sequence":"additional","affiliation":[{"name":"Department for Electronic Systems, Aalborg University, 9220 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6306-6750","authenticated-orcid":false,"given":"Gilberto","family":"Berardinelli","sequence":"additional","affiliation":[{"name":"Department for Electronic Systems, Aalborg University, 9220 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2133-2541","authenticated-orcid":false,"given":"Ole","family":"Madsen","sequence":"additional","affiliation":[{"name":"Department for Materials and Production, Aalborg University, 9220 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"90","DOI":"10.5430\/ijfr.v9n2p90","article-title":"The Fourth Industrial Revolution: Opportunities and Challenges","volume":"9","author":"Xu","year":"2018","journal-title":"Int.
