GOCE SGG and SST quick-look gravity field analysis
The purpose of quick-look analysis in the framework of the GOCE data processing architecture is to analyse partial data sets of satellite gravity gradiometry (SGG) and satellite-to-satellite tracking in high-low mode (hl-SST), in order to derive a diagnosis of the system performance. The semi-analytic (SA) method for gravity field recovery from GOCE observations, which is based on Fast Fourier ...
متن کاملQuick-look outlier detection for GOCE gravity gradients
GOCE will be the first satellite ever to measure the second order derivatives of the Earth’s gravitational potential in space. With these measurements it is possible to derive a high accuracy and resolution gravitational field if systematic errors and/or outliers have been removed to the extent possible from the data. It is necessary to detect as many outliers as possible in the data pre-proces...
متن کاملLocal gravity field continuation for the purpose of in-orbit calibration of GOCE SGG observations
The use of ground gravity data in wellsurveyed areas, continued upward to satellite altitude, is one of the most promising external absolute in-orbit calibration/validation methods for GOCE satellite gravity gradient (SGG) observations. Based on a synthetic gravity test environment – providing in addition to statistical error information also absolute error estimates – several upward continuati...
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 کاملOn the joint inversion of SGG and SST data from the GOCE mission
The computation of spherical harmonic coefficients of the Earth’s gravity field from satellite-to-satellite tracking (SST) data and satellite gravity gradiometry (SGG) data is considered. As long as the functional model related to SST data contains nuisance parameters (e.g. unknown initial state vectors), assembling of the corresponding normal matrix must be supplied with the back-substitution ...
