The design and implementation of constellation simulation and evaluation software

The effective way of solving integrative design, estimate and optimization of complicated multi-satellite system is establishing integrative simulation software. This paper adopts Object-Oriented and some other interrelated technique, setting purpose on erect flexible simulation platform which means the software should be universal, credible, flexible, compositive and easy. It presented designing project, system structure, realization strategy, and modules of satellite constellation simulation software system. At the same time the paper adopts the method of realizing the visualization of satellite track under Windows platform using Visual C++ and OpenGL, which can make the software intuitionistic and visual. Through the computation of simulation, the coverage performance and implementing cost of GEO-TDRSS and MEO-TDRSS are analyzed and compared. The analysis and simulation results indicate that the MEO-TDRSS can provide better coverage performance with more implementing cost.
