摘要
卫星重力梯度测量是研究空间重力梯度探测与应用的新领域,特别适于检测地球重力场的短波特征.目前它尚处在研制超灵敏张量梯度仪器和应用预研究的阶段.本文考察了卫星梯度测量的重要性和优越性.阐述了它在惯性导航和地球重力场模型精化中的作用;探讨了卫星梯度测量在重力勘探、地球动力学与地震预测研究中的多种用途;讨论了它在检测微重力环境、检验重力场延拓理论和改善飞行器轨道受力分析中的重要意义.
Satellite gravity gradiometry is a new domain of studying the detection of gravity gradients in space and their applications, in particular, suitable for detecting the short wavelength characteristics of the earth's gravity field At present it is still at the stage of developing the ultra-sensitive tensor gradiometer and carrying out the pre-research of applications. This paper studies the importance and advantages of satellite gradiometry. The particular role of gravity gradiometry in inertial navigation and the refinement of the earth's gravity field model have been expounded. And many uses of satellite gradiometry in gravity survey, geodyna-mics and earthquake, prediction research have been investigated. In the meantime, the great significance of it in monitoring the microgravity environment, examining the gravity field continuation theory, and improving the analysis subjected orbital vehicle to gravitational force have been discussed.
