在即将到来的千年之交，地球重力场的研究将进入一个新的时代。尽管在过去的几十年里，我们对重力场的认识有了显著的提高，但未来几年，我们将在更好地了解地球系统方面迈出又一大步。全球定位系统的惊人成功，微型计算机技术的惊人发展，以及价格合理的高度复杂的传感器组件的可用性，使人们能够设想一些有前途的空间重力场飞行任务概念。具有互补灵敏度特性的各种重力传感器将具有以高精度测量静态重力场的各个光谱部分的潜力。以月为间隔的重力场快照应允许检测重力场在频谱的某些部分中的时间依赖性。
The investigation of the Earth’s gravity field will enter a new era at the turn of the forthcoming millenium. Despite the fact that a remarkable improvement of our knowledge of the gravity field has been achieved during the past decades the coming years promise another giant step in better understanding the system earth. The surprising success of the Global Positioning System, the breathtaking development of microcomputer technology but also the availability of highly sophisticated sensor components for reasonable prices enable to envisage some promising space borne concepts of gravity field missions. Various gravity sensors with complementary sensitivity characteristics will have the potential of measuring the various spectral parts of the static gravity field with high precision. The snapshots of the gravity field in monthly intervals should allow to detect time dependencies of the gravity field in certain parts of the spectrum.
