The recovery of Earth’s global gravity field from GOCE observations

The ESA’s GOCE (Gravity field and steady-state Ocean Circulation Explorer) mission was the first to jointly apply SGG (satellite gravity gradiometry) and SST-hl (satellite-to-satellite high-low tracking) techniques to map the Earth’s gravity field. It delivered hundreds of millions of observations in four years’ lifetime, from 2009 to 2013. My Ph.D work is to recover a global gravity field model that is described by 62,997 spherical harmonic coefficients (up to degree/order 250) from the huge amount of GOCE observations.

GOCE-GRavitationsfeldANalyse Deutschland – GOCE-GRAND II WP220 – Regionales Validierungs- und Kombinationsexperiment

Within the framework of the project, high-quality validated terrestrial gravity field data sets (in particular deflections of the vertical and gravity data) were generated in Germany and Europe for the external validation of GOCE products. These data were used for the validation of existing satellite gravity models on the one hand and for the calculation of corresponding combined quasigeoid solutions for Germany and Europe on the other hand.
