| 摘 要： | 在地球物理勘探领域中,人造地球卫星的发射为重力测量提供了新的途径。与以往探测重力的手段相比,重力卫星的发射大大改善了人们对地球重力场的认识,随着CHAMP、GRACE和GOCE卫星的发射,将把现有静态中长波部分重力场的精度提高1—2个数量级,并提供长波部分重力场随时间变化的信息。卫星重力学对我国的基础测绘服务和国防建设有着重要的实用价值。

| Abstract: | In the field of geophysical exploration,the satellite mission provides a new method to gravity measurement.Comparing with former methods,the satellite gravity mission has greatly improved our knowledge of the gravity field of the earth.Launching of satellites CHAMP,GRACE,and GOCE in recent years,the accuracy of the static long and medium-wavelength parts of present gravity field will be increased up to 1~2 order of magnitude,and it provides the time variation of long-wavelength part too.The satellite gravity surveying will take an important role in fundamental surveying service and national defence. |
