报告题目

Satellite Gravimetry and the GOCE Mission

报告内容

Satellite gravimetry is the only tool to observe the Earth's gravity field and its time variability globally and consistently. In principle there are two methods to observe gravity from space. These are (1) analysis of orbit perturbations caused by spatial and/or temporal changes of the forcing fields (including the Earth gravity field) and (2) by gravity gradiometry which directly observes tiny gravity gradients between the centre of mass of a satellite in free-fall and an a set of accelerometers symmetrically placed around it. Both principles have pros and cons, which are mainly related to their capabilities to observe specific frequency spectra of the Earth's gravity field. The first part of the presentation provides an introduction to the two techniques of satellite gravimetry, while the second part will explain in some detail the GOCE gravity gradiometry mission and its results.
