Research On Designs Of The Spacecraft Simulation Platform And Its Database Management System

Considering the requirements of the design and analysis of spacecrafts for the simulation platform and database, we studied the detailed design, the design of database system and the encryption techniques on the spacecraft simulation platform in this paper.Firstly, the distributing-interaction simulation platform was built based on HLA (High Level Architecture). The demands, functions and technologies requirements of the platform were analyzed. The project ideas of spacecraft simulation platform were discussed and an example was presented.Secondly, in order to set up the steadier, more securely and reliable database system based on the simulation platform which have agility, expansibility and portability, the project of distributed database system based on network was presented. Particularly, an example of design was presented.Finally, the encryption techniques of database system were studied. Especially, the mixed encryption project that combined DES (Data encryption Standard) with RSA (Rivest-Shamir Adelman) was presented, and the encryption algorithm was realized. Then, the encryption algorithm was applied to the database system in the simulation platform of satellite control system. The results showed that the encryption algorithm had excellent feasibility and security.The research work of this paper is of important applicable values to the developments of spacecraft simulation platforms and their database systems, and the security of spacecraft simulation data.
