In order to select the appropriate ionospheric correction method for common view under different distances between receivers, a detailed test using multi-source data under different ionosphere disturbances are carried out in this paper. Here, we choose three different ionosphere disturbance methods and analyze the advantages and disadvantages of these methods for common-view time transfer and time comparison. At last, we put forward a suitable ionospheric correction method for different distances common view. The RMS shows that the method proposed for 3000 km remote common view can achieve 2.5 ns.<\/jats:p>","DOI":"10.3390\/s20082290","type":"journal-article","created":{"date-parts":[[2020,4,21]],"date-time":"2020-04-21T04:49:38Z","timestamp":1587444578000},"page":"2290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Research on Remote GPS Common-View Precise Time Transfer Based on Different Ionosphere Disturbances"],"prefix":"10.3390","volume":"20","author":[{"given":"Jingkui","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Environment Science and Spatial Informatics, China University of Mining and Technology, Xuzhou 221116, China"},{"name":"State Key Laboratory of Satellite Navigation System and Equipment Technology, Shijiazhuang 050081, China"},{"name":"The 54th Research Institute of China Electronics Technology Group Corporation, Shijiazhuang 050081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingxiang","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Environment Science and Spatial Informatics, China University of Mining and Technology, Xuzhou 221116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baoguo","family":"Yu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Satellite Navigation System and Equipment Technology, Shijiazhuang 050081, China"},{"name":"The 54th Research Institute of China Electronics Technology Group Corporation, Shijiazhuang 050081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chuanzhen","family":"Sheng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Satellite Navigation System and Equipment Technology, Shijiazhuang 050081, China"},{"name":"The 54th Research Institute of China Electronics Technology Group Corporation, Shijiazhuang 050081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1212-0715","authenticated-orcid":false,"given":"Xingli","family":"Gan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Satellite Navigation System and Equipment Technology, Shijiazhuang 050081, China"},{"name":"The 54th Research Institute of China Electronics Technology Group Corporation, Shijiazhuang 050081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"S162","DOI":"10.1088\/0026-1394\/45\/6\/S22","article-title":"A review of time and frequency transfer methods","volume":"45","author":"Levine","year":"2008","journal-title":"Metrologia"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Allan, D.W., and Weiss, M.A. (1980).
