Research on Satellite Simulation for Mobile Terminals

With the development of Internet+, developing an application of satellite simulation which executes on mobile terminals has an important significance for engineers to get visual knowledge of spaceflight. The application design and implementation method of satellite simulation software are discussed. A framework of satellite simulation system is presented, the modules and work-flow of the satellite simulation system are described. Approaches to create the starry background of the satellite operation, environment lighting of the earth and the orbits of satellites in the software are presented in detail. The software uses Unity3D platform to create 3D simulation environment, uses SGP4/SDP4 orbit prediction models to calculate orbits of satellites, and uses databases to store TLE data.
