On Aug. 10, the National Geodetic Survey (NGS) released its latest experimental geoid model, xGeoid18. In early 2019, NGS is scheduled to release its next hybrid geoid model, Geoid18. NGS’ 2018 ...

Abstract: The marine geoid can be determined through the utilization of the marine gravity anomaly model. The accuracy of retrieving marine gravity anomaly model with altimetry data has been improved ...

As high-precision GNSS horizontal and vertical data becomes less expensive to collect, greater attention must be paid when reconciling vertical datasets. In 2013, I wrote two articles entitled ...

Gravity field modeling and geoid determination are critical tasks in geodesy and Earth sciences, providing insights into the Earth’s mass distribution and its gravitational potential. Researchers ...

'GOCE, the Geoid and Oceanography – the Second International GOCE User Workshop' provided the unique forum to present the very latest mission developments and discuss how the eventual data would be ...

ABSTRACT: Different methods have been deployed to compute the geoid, the altimetry reference for surveying applications. One of their main goals is to allow the use of GPS (Global Positioning System) ...

Editor’s Note: Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. There is a “gravity hole” in the Indian ...

ABSTRACT: Many applications in geodesy, hydrography and engineering require determining heights linked to the geoid. Direct leveling, which is the traditional method of obtaining these elevations, is ...

The US National Geodetic Survey has announced the release of an updated alpha version of the GEOID2022 geoid model. GEOID2022 is the foundation for determining precise heights in the modernised US ...

THE aim of my article was to show that the theoretical result derived by Cook 1 (that the low-degree harmonics of the geopotential originate from the area of the core–mantle boundary) is in accordance ...
