Abstract
Simulation, 3D visualization and analyses of satellite imaging tasks are capable to display orbital maneuver and ground cover scheme, which are much helpful to ensure the feasibility and reliability of the mission planning and to improve the efficiency of the satellite utilization. A system of 3D visualization and simulation for satellites is proposed and presented in the current work. Multi-resolution mass terrain data, images and vector data are processed and seamless stitched, and dynamic roaming of large range scenes based on digital earth is built as well. Then, the satellite flight status, maneuver, onboard sensor states and ground coverage ranges are visualized by using data of the satellite mission scheduling. Moreover, the system provides the visualization analyses of multi-dimension, high fidelity, free observation and so on. The proposed system is evaluated by practical satellite data and the experiments show that the system is capable to offer an intuitive, convenient and effective way for the space exploration and engineering design of satellites.
