地球重力场和海洋环流探测卫星及其应用

The Gravity Field and Steady- State Ocean Circulation Explorer （GOCE） and Its Application

近年来，卫星重力学研究越来越受到各国的重视，继德国“挑战小卫星有效载荷及地球科学探索卫星”（CHAMP）和美欧合作的“地球重力场恢复和气候探索卫星”（GRACE）之后，欧洲航天局又于2009年3月发射了地球重力场和海洋环流探测卫星（GOCE）。本文概要介绍了GOCE卫星的基本情况，重点阐述了卫星载荷及卫星的科学应用情况，分析了国际上卫星重力学的研究进展。

These years, the research of satellite gravimetry is getting more and more attention. In 2000, Germany launched the Challenging Mini - satellite Payload （CHAMP）. Then in 2002, an US - Europe developped satellite—— Gravity Recovery and Climate Experiment （GRACE） was launched successfully. After these, quite recently, in March 2009, European Space Agency launched the Gravity field and steady - state Ocean Circulation Explorer （GOCE）. In this paper, several important aspects of GOCE are introduced. The emphasis is focused on the payloads and the scientific applications of this satellite. The progress of the research on satellite gravimetry is also discussed in this paper.
