With the development of modern science and technology, outer space is stepping into our life, work and other areas,
which attracts more and more people's attention on spatial resources. However, it is difficult for an unspecialized person
to know much professional knowledge, such as astronautics about the space. In this paper, we have developed a spatial
situation simulation system based on STK, which has integrated the complex field environment associated with the land,
sea, air, space and electronic scenarios by an easier understanding way. The design and implementation of the spatial
situation simulation system will benefit people to research and develop the outer space by providing a dynamic
simulation platform and abundant data resources.
