A Space-Circle Architecture Design and Performance Analysis of Spatial Backbone Network Based on Geostationary Satellite Collocation.

With the development of satellite technology, and continuous improvement of relay, communication, navigation, remote sensing and meteorological satellite systems in China, massive heterogeneous spatial information needs for convergence, integration, storage, transmission, processing, forwarding and so on had put forward higher requirements to the construction of spatial backbone network. Proceeding from the architecture design of spatial backbone network, using the method of geostationary satellite collocation to build the backbone node was proposed. And then several typical geostationary satellite collocation styles were analyzed and compared. Using Orbital dynamics and spherical geometry theory, a fly around model with space-circle configuration was designed, and its AER performance was analyzed through simulation software and optimization algorithm. The simulation results showed that the configuration completely meet design requirements of spatial backbone network.
