开源数据库在卫星控制中心的应用研究

实现信息系统的自主、安全、可控已成为测控中心系统的研究方向和建设目标。研究应用自主可控数据库是实现测控中心系统全面自主可控的重要环节。目前,卫星控制中心的数据存储系统大多以Oracle数据库为主,软件和技术服务费用昂贵,更新维护成本高,且可能带有信息安全和任务安全方面的风险。针对上述这些问题,研究分析了开源数据库MySQL在卫星控制中心系统中应用的可行性,对MySQL数据库做了全面测试,包括功能、性能、系统级的高可用测试,以及MySQL与Oracle数据库的性能对比测试。研究和测试结果表明,MySQL开源数据库可以用于卫星控制中心系统以及类似的测控中心应用系统,对今后测控中心系统应用自主可控数据库具有参考价值和借鉴意义。

Research on Application of Open Source Databases for Satellite Control Centers

Implementation of proprietary and controllable and secure information systems has already become the research trend and system construction goal for TT&C (Tracking, Telemetry and Command) center systems,while research on application of proprietary and controllable database is an important part of full implementation of proprietary and controllable technology. Currently, data storage systems of SCC (Satellite Control Center) are dominated by Oracle database with expensive database software and technical services, high software update and maintenance costs, and, with that, come the problems of information security and task risks. Facing these problems, this paper addresses application of open source MySQL for SCC, describes MySQL function tests, performance tests, system level HA (High Availability) tests and performance comparison tests of MySQL and Oracle. Research and test results show that MySQL could be used for SCC system platform and similar TT&C center application systems. Application of self controlled database provides valuable reference and technical support for future TT&C center systems.
