With the variety and complexity of remote sensing missions, the observation mode changed gradually from single satellite to satellite network to complete deep observation and quantitative inversion of surface resources. Based on the secondary development of World Wind, this paper introduced a simulation system for multi-satellite imaging. Here it described the system structure and function, highlighting the technical solution of the system: the establishing of three-dimensional scene, the satellite orbit simulation, coverage analysis and visualization operations, and gave some of the results in Figure. At last the strengths and weaknesses of the system were carried out and it prospected.
