The local wavenumber of a magnetic anomaly is used to interpret the edges or positions of the sources, and can involve first- or second-order local wavenumbers. In this paper, we derived a linear equation between the second-order local wavenumber and the source location; therefore, we propose a constraint of first and second-order local wavenumbers. Tests on synthetic data show that the source parameters, computed using a combination of equations that involved different-order local wavenumbers, are closer to the true values and show a smaller spread in estimated values. For gridded data, we proved that the different-order combination allowed us to accurately estimate the source position. When applied to the aeromagnetic data from Hebei province, China, we refined the location of most magnetic features, which we interpreted as possible iron deposits.<\/jats:p>","DOI":"10.3390\/rs14030591","type":"journal-article","created":{"date-parts":[[2022,1,27]],"date-time":"2022-01-27T04:49:51Z","timestamp":1643258991000},"page":"591","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["High-Precision Source Positions Obtained by the Combined Inversion of Different-Order Local Wavenumbers Derived from Aeromagnetic Data"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5621-9296","authenticated-orcid":false,"given":"Guoqing","family":"Ma","sequence":"first","affiliation":[{"name":"College of Geo-Exploration Sciences and Technology, Jilin University, Changchun 130026, China"},{"name":"Key Laboratory of Geophysical Exploration Equipment Ministry of Education of China, Jilin University, Changchun 130026, China"},{"name":"Institute of National Development and Security Studies, Jilin University, Changchun 130026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9256-2219","authenticated-orcid":false,"given":"Nan","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Geo-Exploration Sciences and Technology, Jilin University, Changchun 130026, China"},{"name":"Key Laboratory of Geophysical Exploration Equipment Ministry of Education of China, Jilin University, Changchun 130026, China"},{"name":"Institute of National Development and Security Studies, Jilin University, Changchun 130026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lili","family":"Li","sequence":"additional","affiliation":[{"name":"College of Geo-Exploration Sciences and Technology, Jilin University, Changchun 130026, China"},{"name":"Key Laboratory of Geophysical Exploration Equipment Ministry of Education of China, Jilin University, Changchun 130026, China"},{"name":"Institute of National Development and Security Studies, Jilin University, Changchun 130026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"482","DOI":"10.1190\/1.1439384","article-title":"Aeromagnetics","volume":"29","author":"Reford","year":"1964","journal-title":"Geophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"103","DOI":"10.3997\/1365-2397.29.4.49509","article-title":"Unmanned aircraft system proves itself as a geophysical measuring platform for aeromagnetic surveys","volume":"29","author":"Tezkan","year":"2011","journal-title":"First Break"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"112","DOI":"10.4236\/pos.2011.23012","article-title":"Unmanned Airborne Magnetic and VLF Investigations: Effective Geophysical Methodology for the Near Future","volume":"2","author":"Eppelbaum","year":"2011","journal-title":"Positioning"},{"key":"ref_4","doi-asserted-by":"crossref","unstructured":"Ibrahim, A., Gemail, K., Abdelrahman, K., Al-Otaibi, N., Ibrahim, E., and Saada, S.
