However, the GNSS signal of reference stations and monitoring stations used for bridge monitoring can easily be blocked by bridge towers, vehicles, or other objects, resulting in low positioning accuracy and insufficient availability of GNSS, which affects the effectiveness of bridge structural health monitoring. Therefore, according to the characteristics of bridge structure, this paper proposes to take the bridge tower monitoring station as a moving-base station to build the baselines with other monitoring stations and use the moving-base RTK-GNSS method to realize the relative positioning, so as to improve the availability of GNSS in the application of bridge structure health monitoring. In this paper, the moving-base RTK-GNSS model is derived and verified via GNSS monitoring data of the Ganzhou dedicated high-speed railway bridge. The results show that the ambiguity in the fixing rate can be improved using the moving-base RTK-GNSS method with the tower monitoring station as the reference station. The deformation and vibration characteristics of each monitoring point can be reflected, and the displacement and vibration amplitude estimation accuracy can achieve results better than 4 mm. Therefore, the moving-base RTK-GNSS method can be used as an alternative scheme when the observation environment of the base station is poor or the banded engineering monitoring is applied, so as to improve the monitoring capability of GNSS.<\/jats:p>","DOI":"10.3390\/rs15123132","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T02:02:20Z","timestamp":1686880940000},"page":"3132","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Performance Assessment of Structural Monitoring of a Dedicated High-Speed Railway Bridge Using a Moving-Base RTK-GNSS Method"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8877-610X","authenticated-orcid":false,"given":"Ruijie","family":"Xi","sequence":"first","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan University of Technology, Wuhan 430070, China"},{"name":"Sanya Science and Education Innovation Park of Wuhan University of Technology, Innovation Road, Sanya 572000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3267-9682","authenticated-orcid":false,"given":"Weiping","family":"Jiang","sequence":"additional","affiliation":[{"name":"GNSS Research Center, Wuhan University, Wuhan 430079, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3310-3789","authenticated-orcid":false,"given":"Wei","family":"Xuan","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan University of Technology, Wuhan 430070, China"},{"name":"School of Artificial Intelligence, Wuchang University of Technology, Wuhan 430223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5586-8478","authenticated-orcid":false,"given":"Dongsheng","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan University of Technology, Wuhan 430070, China"},{"name":"Sanya Science and Education Innovation Park of Wuhan University of Technology, Innovation Road, Sanya 572000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lihua","family":"He","sequence":"additional","affiliation":[{"name":"Hubei Provincial Geographic National Conditions Monitoring Center, Wuhan 430071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Ma","sequence":"additional","affiliation":[{"name":"China Railway Siyuan Survey and Design Group Co., Ltd., Wuhan 430079, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1061\/(ASCE)0733-9453(1995)121:1(35)","article-title":"Dynamic Deformation Monitoring of Tall Structure Using GPS Technology","volume":"121","author":"Lovse","year":"1995","journal-title":"J.
