However, previous studies have always lacked sufficient discussion on the position error of magnetometers in magnetic tensor gradiometers caused by inaccurate installment of magnetometers. In this paper, we analyze and correct this position error based on a magnetic dipole source. The result of the simulation exemplifies that the magnetometer\u2019s position error will affect the locating accuracy and, therefore, it is worth correcting this error. The relationship between position error and magnetic gradient tensor components is established, followed by an error correction method based on this relationship. Simulations illustrate that this method can effectively decrease the effect caused by the position error of magnetometers and improve the locating performance with locating error and magnetic moment errors dropping from 2 to 0.2 m and     6 \u00d7   10  5  A \u22c5  m 2      to     5 \u00d7   10  4  A \u22c5  m 2     , respectively.<\/jats:p>","DOI":"10.3390\/s20051290","type":"journal-article","created":{"date-parts":[[2020,2,28]],"date-time":"2020-02-28T09:30:36Z","timestamp":1582882236000},"page":"1290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Analysis and Correction of the Magnetometer\u2019s Position Error in a Cross-Shaped Magnetic Tensor Gradiometer"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9555-8888","authenticated-orcid":false,"given":"Youyu","family":"Yan","sequence":"first","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianguo","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"33ND","DOI":"10.1190\/1.2133784","article-title":"The historical development of the magnetic method in exploration","volume":"70","author":"Nabighian","year":"2005","journal-title":"Geophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1109\/LMAG.2019.2915652","article-title":"Calibration of Magnetometer Arrays in Magnetic Field Gradients","volume":"10","author":"Mu","year":"2019","journal-title":"IEEE Magn.
