Ellipsoidal Effects, Modelling and Technique Refinements in High Accuracy Quasigeoid Computation

Popis výsledku v původním jazyce

The paper focuses on methodological and computational aspects associated with high accuracy quasigeoid modelling. Accuracy demands driven by GNSS levelling applications are substantially taken into consideration. The concept of the so-called gravimetricboundary value problem was used as the basis for the determination of the disturbing potential from gravity disturbances. In the approach developed the Green?s function constructed for the exterior of an oblate ellipsoid of revolution is essentially usedfor the solution of the problem. The mathematical apparatus is constructed consistently. The idea of spherical approximation was avoided. This also means that the kernel used for the integral representation of the solution is an ellipsoidal analogue tothe so-called Hotine-Koch function well-known in physical geodesy. Fundamental steps leading from an ellipsoidal harmonics series representation of the kernel into its closed form expression are explained. Legendre elliptic integrals were
