星载重力梯度仪的研究发展

摘要

本文首先阐述了卫星重力梯度测量的实现与特点，其次介绍了重力梯度卫星GOCE任务及卫星核心载荷——重力梯度仪情况，论述了重力梯度仪的研究发展历程，重点探讨了一种新的基于原子干涉测量技术的绝对重力梯度仪，通过研究分析得出了这种绝对重力梯度仪具有测量精度高和应用领域广的优越性，最后提出我国发展卫星重力测量技术的建议。%The realization and features/characteristics of spaceborne gravity gradiometer measurement are stated firstly,the mission of GOCE and the condition of gravity gradiometer(satellite GOCE core payload)are introduced secondly,the research and development progress of gravity gradiometer are expounded,the absolute gravity gradiometer--a new gradiometer based atomic interferometry measurement is discussed emphatically. The conclusion that the measurement precision of absolute gradiometer is high and the application field of absolute gradiometer is wide is reached from research and analysis. Develop suggestions of spaceborne gravity gradiometer in our country are put forward finally.
