Focusing their attention on the reduction of bias instability and random walk-driven drift of cost-effective MEMS accelerometers and gyroscopes, the authors hereinafter propose a suitable method, based on a redundant configuration and complemented with a proper measurement procedure, to improve the performance of low-cost, consumer-grade MEMS sensors. The performance of the method is assessed by means of an adequate prototype and compared with that assured by a commercial, expensive, tactical-grade MEMS inertial measurement unit, taken as reference. Obtained results highlight the promising reliability and efficacy of the method in estimating position, velocity, and attitude of vehicles; in particular, bias instability and random walk reduction greater than 25% is, in fact, experienced. Moreover, differences as low as 0.025 rad and 0.89 m are obtained when comparing position and attitude estimates provided by the prototype and those granted by the tactical-grade MEMS IMU.<\/jats:p>","DOI":"10.3390\/s21144851","type":"journal-article","created":{"date-parts":[[2021,7,18]],"date-time":"2021-07-18T21:18:52Z","timestamp":1626643132000},"page":"4851","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Performance Enhancement of Consumer-Grade MEMS Sensors through Geometrical Redundancy"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4460-6640","authenticated-orcid":false,"given":"Giorgio","family":"de Alteriis","sequence":"first","affiliation":[{"name":"Department of Industrial Engineering, University of Naples Federico II, Piazzale Tecchio 80, 80125 Naples, Italy"},{"name":"Department of Management Information and Production Engineering, University of Bergamo, 24044 Bergamo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8843-0109","authenticated-orcid":false,"given":"Domenico","family":"Accardo","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Naples Federico II, Piazzale Tecchio 80, 80125 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9441-2927","authenticated-orcid":false,"given":"Claudia","family":"Conte","sequence":"additional","affiliation":[{"name":"Department of Management Information and Production Engineering, University of Bergamo, 24044 Bergamo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4875-2845","authenticated-orcid":false,"given":"Rosario","family":"Schiano Lo Moriello","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Naples Federico II, Piazzale Tecchio 80, 80125 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.paerosci.2018.05.002","article-title":"Avionics Human-Machine Interfaces and Interactions for Manned and Unmanned Aircraft","volume":"102","author":"Lim","year":"2018","journal-title":"Prog.
