Validation of GOCE global gravity eld models using terrestrial gravity data in Norway
The GOCE (Gravity eld and steady-state Ocean Circulation Explorer) satellite gravity gradiometry mission maps the Earth’s gravity eld. Harmonic analysis of GOCE observations provides a global gravity eldmodel (GGFM). Three theoretical strategies, namely the direct, the space-wise and the time-wise approach, have been proposed for GOCE harmonic analysis. Based on these threemethods, several GGFM...
متن کاملValidation of GOCE global gravitational field models in Norway
Numerous global gravitational field models have been derived from the GOCE satellite gravitational gradiometry mission. They differ by the harmonic analysis approach and the time span covered by the measurements. The quality of individual solutions is assessed by validating the global gravitational field models with respect to independent datasets. Global gravitational field models based on the...
متن کاملGlobal Gravity Field Determination by Combining Goce and Complementary Data
GOCE gravity fields define a new standard concerning spectral resolution of satellite-only models, and provide a very high precision in the longand medium wavelength part of the gravity field up to a spherical harmonic degree of about 250. Combining GOCE with GRACE data, which gives in addition very accurate information for the long wavelength part, results in the current performance status of ...
متن کاملGoce Gravity Field Processing
In the course of the satellite mission GOCE (Gravity field and steady-state Ocean Circulation Explorer), dedicated for the exploitation of the Earth's gravity field, with a planned launch in summer 2006, the data processing will be a huge numerical and computational intensive task. In this paper we will describe a direct approach developed and implemented in Graz for the derivation of a model f...
متن کاملEvaluation of the first GOCE static gravity field models using terrestrial gravity, vertical deflections and EGM2008 quasigeoid heights
Recently, four global geopotential models (GGMs) were computed and released based on the first two months of data collected by the GOCE (Gravity field and steady-state Ocean Circulation Explorer) dedicated satellite gravity field mission. Given that GOCE is a technologically complex mission and different processing strategies were applied to real space-collected GOCE data for the first time, ev...
