Quick-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 کاملCombination of GOCE gravity gradients in regional gravity field modelling using radial basis functions
The satellite gravity mission GOCE measured the second-order derivatives of the Earth’s gravitational potential with high accuracy. The GOCE data enrich our gravity field knowledge especially at spatial resolutions from 750km down to 80km. In this paper we carry out regional gravity field analysis using radial localising basis functions that permit the combination of different data types tailor...
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 کاملGravity Gradients and Spherical Harmonics - a Need for Different Goce Products?
GOCE will deliver Level 2 products such as grids of geoid heights and gravity anomalies, along with a spherical harmonic model of the Earth’s gravity field. Furthermore, Level 1B calibrated gravity gradients will be available. The majority of these products may seem superfluous, as they are all linear functionals of one and the same quantity, the Earth’s gravitational potential. We will show wh...
