Design of Cloud-Based TT&C Center System

As an important part of aerospace mission engineering, the TT&C center system currently adopts technologies such as duplex duplexing, server clusters, disk RAID, data backup and recovery to ensure the uninterrupted operation, stability and reliability of the aerospace mission system. In addition to meet high-reliability and real-time requirements of the system, there is also a need to decouple the application software and physical resource, facilitate resource sharing, system expansion and application software upgrade, as well as easy system operation and maintenance, so the paper addresses the design of the cloud-based TT&C center system that is used to dynamically allocate resources, virtualize physical devices, provide services to the upper layers, services customization on-demand, resource sharing and interoperability, and flexible expansion. The deployed TT&C center cloud system shows that a novel integration of the TT&C application services which enables TT&C professionals to better accomplish spacecraft management and control missions. The cloud-based TT&C center system is tested and verified by actual aerospace missions.
