Regional quasigeoid solutions for the Ukraine area
, 2015 The UQG2012 regional quasigeoid solution of an accuracy better than 4 cm with respect to the GPS-levelling data of the 1st and 2nd order was constructed by means of the least squares collocation method. In the first iteration the gravimetry-only quasigeoid UQG2011 was developed from the gravity anomalies for the subsequent detection of gross errors in ...

Assessment of qualitaty of quasigeoid models in Riga city
, 2023 The study of the shape and size of the globe on a global scale is crucial to understanding the challenges and impacts of climate, the life sciences, hydrology, hydrography and geology on the planet as a whole. The Earth's topography – the surface, the relief topography that characterizes two different types of regions and certain local urban areas

GEOID-QUASIGEOID CORRECTION IN FORMULATION OF THE FUNDAMENTAL FORMULA OF PHYSICAL GEODESY
Revista Brasileira de Cartografia, 2006 To formulate the fundamental formula of physical geodesy at the physical surface of the Earth, the gravity anomalies are used instead of the gravity disturbances, because the geodetic heights above the geocentric reference ellipsoid are not usually ...

Tiếp cận khái niệm về mặt Quasigeoid
Tạp chí Khoa học Đo đạc và Bản đồ, 2010 Molodenskii M.X. đưa ra mặt Quasigeoid để biểu diễn độ cao chuẩn từ mặt vật lý của Quả đất theo đường vuông góc với mặt Ellipsoid. Tuy nhiên trong các tài liệu về Trắc địa cao cấp giải thích về mặt này rất khác nhau, thậm trí coi mặt này chỉ là sản phẩm của quá trình xác định độ cao chuẩn của các điểm trên mặt vật lý của Quả đất.

Regional quasigeoid determination: an application to Arctic Gravity Project
, 2015 Purpose. Investigation to study quasigeoid computations based on the regional gravimetric data and different types of nonorthogonal basis functions was assessed to be important. When measurements from only restricted regions of the Earth surface are available, global spherical harmonics loose their orthogonality in a limited region, so the ...
