Engineering Realization of Software in Central Terminal Unit of Satellite Data Management System

Focused on software functional requirements of central terminal unit of a satellite's data management system, operating system and application software have been designed and realized. The design has also been validated in the experiment inside data management subsystem and the interface matching experiment with other subsystems. In the software design, concept of Spacecraft Onboard Interface Service(SOIS) of CCSDS and Packet Utilization Standard(PUS) of European Space Agency have been taken as reference, which is helpful for making the software realized by components and become products.
