The observation and research for solid earth tides (SET) have always been the focus of earth science. Ground-station observation have their inherent limitations, and the development of space technology makes it possible to observe the SET phenomenon. In this paper, the temporal and spatial distribution characteristics of the SET are obtained by using the theoretical model. Based on these characteristics, the macroscopic observation potential of space technology is discussed. It mainly includes the wide-area displacement monitoring ability by the combination of InSAR technology and ranging technologies like GNSS, VLBI, SLR,and the time-varying gravity acquisition ability solved from gravity satellite data. According to the requirements of InSAR Technology on time baseline and swath width, three kinds of platform, namely low earth orbit (LEO) satellite, Inclined geosynchronous satellite and moon-based platform, are simulated. And the advantages and disadvantages of various platforms are analyzed. The results showed that the network of new gravity satellite as well as the new conceptual platform of remote sensing have the macro observation potential for SET, in which the moon-based InSAR may be developed into the most ideal means, and the development of space technology can provide a certain supplement for the spatial-decorrelation period of the moon-based platform and realize the complementary advantages.
