However, most of these indoor localization technologies often fail in a reasonable solution to the key problems such as low cost and highly accurate and efficient for users. In this paper, we propose an indoor location method based on integrated pseudolite and UWB; the virtual pseudo-range measurements of UWB are used to replace the pseudo-range measurements of pseudolite to solve the indoor multipath problem, which is tightly coupled with the corrected carrier phase measurements of pseudolite. Then, the channel-difference observation equation and UWB-aided ambiguity resolution are proposed for precise positioning. In order to test the proposed method, several experiments are conducted. The results show that the virtual pseudo-range errors from UWB are smaller than that of GNSS, and such a small bias will be better for the fast fixing of ambiguity. In addition, the positioning accuracy of the proposed indoor location method is improved from cm-level for the float solution to mm-level for the fixed solution; these performances would be more convincing to users than that given in the most pseudolite and UWB.<\/jats:p>","DOI":"10.1155\/2022\/3962014","type":"journal-article","created":{"date-parts":[[2022,7,1]],"date-time":"2022-07-01T19:20:12Z","timestamp":1656703212000},"page":"1-14","source":"Crossref","is-referenced-by-count":4,"title":["An Approach to Improve the Indoor Positioning Performance of Pseudolite\/UWB System with Ambiguity Resolution"],"prefix":"10.1155","volume":"2022","author":[{"given":"Xingli","family":"Gan","sequence":"first","affiliation":[{"name":"School of Information and Electronic Engineering, Zhejiang University of Science and Technology, Hangzhou 310023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3932-7014","authenticated-orcid":true,"given":"Zhihui","family":"Huo","sequence":"additional","affiliation":[{"name":"School of Information and Electronic Engineering, Zhejiang University of Science and Technology, Hangzhou 310023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Communication Engineering, Institute of Information Science Technology, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shan","family":"Yang","sequence":"additional","affiliation":[{"name":"China Unicom Smart City Research Institute, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaihui","family":"Liu","sequence":"additional","affiliation":[{"name":"Dongguan University of Technology and the Great Bay University, Dongguan 523000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2005.858598"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2006.1613745"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.3390\/s19204420"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2019.2905771"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2015.7060497"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2017.2660522"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TCE.2008.4637573"},{"key":"8","first-page":"1184","article-title":"Results of IMES (indoor messaging system) implementation for seamless indoor navigation and social infrastructure platform","author":"D.
