A new approach for land vehicle gravimetry using a Strapdown Inertial Navigation System and velometer-integrated navigation computation (SINS\/VEL) without using GNSS information has been put forward. Aided by the velometer with continuous longitudinal velocity output instead of GNSS signals, a SGA-WZ02 strapdown gravimeter that used the SINS\/VEL method was tested in 2015. Four repeated lines were measured along a south-north direction highway in Eastern Changsha to verify the new method\u2019s feasibility and performance. The gravity disturbance results showed an internal accuracy in scalar gravimetry about 1.17 mGal and 1.91 mGal for external accuracy assessment, with a spatial resolution of 1.7 km. Comparing this new method with the traditional SINS\/GNSS gravimetry approach, it appeared that the results using SINS\/VEL showed comparable internal and external accuracy. Theoretical analysis and practical test results showed that the new method was feasible for gravity determination by land dynamic vehicle.<\/jats:p>","DOI":"10.3390\/s17040766","type":"journal-article","created":{"date-parts":[[2017,4,4]],"date-time":"2017-04-04T10:15:12Z","timestamp":1491300912000},"page":"766","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["A New Method for Land Vehicle Gravimetry Using SINS\/VEL"],"prefix":"10.3390","volume":"17","author":[{"given":"Ruihang","family":"Yu","sequence":"first","affiliation":[{"name":"College of Mechatronics and Automation, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meiping","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Mechatronics and Automation, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaidong","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Mechatronics and Automation, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaokun","family":"Cai","sequence":"additional","affiliation":[{"name":"College of Mechatronics and Automation, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juliang","family":"Cao","sequence":"additional","affiliation":[{"name":"College of Mechatronics and Automation, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minghao","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Mechatronics and Automation, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Mechatronics and Automation, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,4,4]]},"reference":[{"key":"ref_1","unstructured":"Kwon, J.H.
