Tri-axis RINS has three gimbals, and the Inertial Measurement Unit can rotate along three directions to modulate the inertial devices\u2019 errors, so that the navigation accuracy of the system can be greatly improved. However, the outputs of attitudes are easily affected by the non-orthogonal angles of gimbals, which should be accurately calibrated and compensated. In this paper, the effects of the non-orthogonal angles on the attitudes are discussed detailed and simulations based on Matlab are conducted to verify that firstly; then, a self-calibration method based on the outputs of the fiber optic gyroscope and photoelectric encoder is proposed. Experimental results in a real tri-axis RINS show that the attitude outputs accuracy are improved from 150\u201d to less than 10\u201d, which verify the practicability of the calibration method proposed in this paper.<\/jats:p>","DOI":"10.1177\/0142331217729203","type":"journal-article","created":{"date-parts":[[2017,10,9]],"date-time":"2017-10-09T06:45:59Z","timestamp":1507531559000},"page":"3665-3674","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["A self-calibration method for non-orthogonal angles of gimbals in rotational inertial navigation system based on fiber optic gyro"],"prefix":"10.1177","volume":"40","author":[{"given":"Zengjun","family":"Liu","sequence":"first","affiliation":[{"name":"School of Instrumentation Science and Opto-electronics Engineering, Beihang University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Instrumentation Science and Opto-electronics Engineering, Beihang University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Instrumentation Science and Opto-electronics Engineering, Beihang University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tianxiao","family":"Song","sequence":"additional","affiliation":[{"name":"School of Instrumentation Science and Opto-electronics Engineering, Beihang University, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,10,9]]},"reference":[{"key":"bibr1-0142331217729203","doi-asserted-by":"publisher","DOI":"10.3844\/jcssp.2014.2619.2627"},{"key":"bibr2-0142331217729203","doi-asserted-by":"publisher","DOI":"10.5614\/j.eng.technol.sci.2014.46.2.7"},{"key":"bibr3-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1007\/s00542-016-3171-1"},{"key":"bibr4-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1109\/ChiCC.2014.6896709"},{"key":"bibr5-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2016.2616356"},{"key":"bibr6-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1109\/OCEANSE.2007.4302282"},{"key":"bibr7-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1155\/MPE.2005.1"},{"key":"bibr8-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1364\/AO.52.007724"},{"key":"bibr9-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2009.2022104"},{"key":"bibr10-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1088\/0957-0233\/18\/7\/016"},{"key":"bibr11-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1007\/s00542-017-3286-z"},{"key":"bibr12-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2014.2361671"},{"key":"bibr13-0142331217729203","author":"Wang K","year":"2017","journal-title":"Systems Engineering and Electronics"},{"issue":"6","key":"bibr14-0142331217729203","first-page":"76","volume":"28","author":"Yuan B","year":"2006","journal-title":"Journal \u2013National University of Defense Technology"},{"key":"bibr15-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1088\/0957-0233\/23\/2\/025102"},{"key":"bibr16-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1587\/elex.13.20160841"},{"key":"bibr17-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1364\/OE.24.021228"},{"key":"bibr18-0142331217729203","doi-asserted-by":"publisher","DOI":"10.1016\/j.sna.2015.05.002"}],"container-title":["Transactions of the Institute of Measurement and Control"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0142331217729203","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0142331217729203","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0142331217729203","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T14:56:16Z","timestamp":1777647376000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0142331217729203"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,10,9]]},"references-count":18,"journal-issue":{"issue":"13","published-print":{"date-parts":[[2018,9]]}},"alternative-id":["10.1177\/0142331217729203"],"URL":"https:\/\/doi.org\/10.1177\/0142331217729203","relation":{},"ISSN":["0142-3312","1477-0369"],"issn-type":[{"value":"0142-3312","type":"print"},{"value":"1477-0369","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,10,9]]}}}
