Gravity Field Analysis from the Satellite Missions CHAMP and GOCE
This work describes global gravity field modeling from observations of the CHAMP and the GOCE satellite mission. In the case of CHAMP the so-called Energy Balance Approach is applied to measurements of GPS high-low tracking of the low orbiting CHAMP spacecraft. In the case of GOCE gravity gradiometry is the main observable. The experience gained processing real data of the CHAMP satellite missi...
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 کاملThe Earth’s Gravitational Field Recovery Based on an Optimal Combination of Grace and Goce Satellite Data
Modelling the global gravitational field of the Earth in terms of spherical harmonic coefficients has been performed by a stand-alone inversion of a 4-month set of the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) Satellite Gravity Gradiometry (SGG) data and a 9-month set of the GOCE kinematic orbits, as well as by a combined inversion of the aforementioned data sets and 1-ye...
متن کاملStatistical downscaling of GRACE gravity satellite-derived groundwater level data
With the continued threat from climate change, population growth and followed by increasing water demand, the need for hydrological data with high spatial resolution and proper time coverage to be felt more than ago. Therefore, having data such as terrestrial water storage changes and groundwater level changes with high resolution spatial helps to plan and make decisions for water resource mana...
متن کاملContribution Analysis of the Gravity Field Recovered from Goce
Gravity field modeling in the case of GOCE is based on a combination of the SST contribution for the low wavelength part and on gravitational gradiometry for the spatial details. The gradiomter part of the solution is derived from a combination of the gradient components Vxx, Vyy, Vzz. Variance components in the domain of spherical harmonics allow the analysis of the characteristic contribution...
