The reduced measurement noise level can make possible much-improved measurements of the short-period and short-wavelength variations in the geopotential. This would be particularly from the along-track analysis of the results, which can permit repeat measurements about half a day apart along ground tracks within 200 km of each other over a substantial part of the globe. Such a mission would permit considerably improved testing of geophysical models for the geopotential variations due to changes in the Earth\u2019s mass distribution.<\/jats:p>","DOI":"10.3390\/rs14040948","type":"journal-article","created":{"date-parts":[[2022,2,16]],"date-time":"2022-02-16T21:36:24Z","timestamp":1645047384000},"page":"948","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["An Improved Next Generation Gravity Mission"],"prefix":"10.3390","volume":"14","author":[{"given":"Peter L.","family":"Bender","sequence":"first","affiliation":[{"name":"JILA, University of Colorado, Boulder, CO 80309-0440, USA"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,16]]},"reference":[{"key":"ref_1","unstructured":"Reigber, C.
