The 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 کاملGravity 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 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 کاملExternal calibration of GOCE accelerations to improve derived gravitational gradients
The aim of ESA's satellite mission GOCE is to determine the Earth's gravity field with high accuracy and resolution. To achieve this aim, GOCE carries a gravitational gradiometer that needs calibration. Existing global gravity fieldmodels in combinationwith GOCE star sensor data may be used to synthesize reference differential accelerations with which the common and differential accelerations, ...
متن کاملA timewise kinematic method for satellite gradiometry: GOCE simulations
We have defined new algorithms for the data processing of a satellite geodesy mission with gradiometer (such as the next European mission GOCE) to extract the information on the gravity field coefficients with a realistic estimate of their accuracy. The large scale data processing can be managed by a multistage decomposition. First the spacecraft position is determined, i.e., a kinematic method...
