Architecture of a distributed multimission operations system

This paper presents an architecture to develop a multimission operations systems, which we call DIOSA. In this architecture, a component used as a building block is called a functional block. Each functional block has a standard structure, and the interface between functional blocks are defined with a set of standard protocols. This paper shows the structure of the database used by functional blocks, the structure of interfaces between functional blocks, and the structure of system management. Finally, examples of typical functional blocks and an example of a system constructed with this architecture is shown.
