explorer-type satellite

On the basis of the analysis of the status and limitations of existing satellite observation methods for gravity recover, the necessary development strategies for effective implementation of GOCE ( Gravity Field and Steady-State Ocean Circulation Explorer) plan are presented.

通过分析利用卫星观测技术恢复地球重力场的现状与不足，论述了实施GOCE任务&地球重力场和稳态海洋环流实验的必要性；

On Jan. 31, 1958, the United States entered the Space Age with its first successful launch of a satellite into orbit, Explorer I.
