Calculation of space situation and its visualization modeling

Space situation is a comprehensive description of the state, progress and trend, such as the deployment of space equipment, space action, and space environment etc. For the complexity of space environment and space equipment, and the particularity of space action, the functions and structure of a space situation system are designed with the aid of the mathematical model and visualization technology. The synthesis and calculation models of space situation are proposed, the visualization modeling methods of space environment, spatial features and spatial action are proposed. Finally, the result diagrams of parts of the situation are given.
