Fractionated spacecraft represent a novel space architecture with clusters of independent modules that must communicate wirelessly while maintaining strict security and resource constraints. This work is innovative in providing a component-based architecture that abstracts system complexities and provides framework support for fault management, security isolation, and efficient resource utilization in highly dynamic space platforms.
This paper presents a model-driven software component framework (FX) for fractionated spacecraft systems, addressing the challenge of developing and deploying reusable components in highly constrained space environments. The framework defines component models with formal interface specifications and execution semantics for mission-critical distributed applications.
The FX framework demonstrates how Interface Definition Language (IDL) concepts enable flexible component interactions through peer-to-peer, group-based, and device interaction patterns. The architecture successfully integrates deployment management, operations management, dictionary management, and fault management capabilities into a unified platform serving distributed spacecraft applications.

abstract = {Complexity in embedded software systems has reached the point where we need run-time mechanisms that provide fault management services. Testing and verification may not cover all possible scenarios that a system encounters, hence a simpler, yet formally specified run-time monitoring, diagnosis, and fault mitigation architecture is needed to increase the software system's dependability. The approach described in this paper borrows concepts and principles from the field of `Systems Health Management' for complex aerospace systems and implements a novel two level health management architecture that can be applied in the context of a model-based software development process.},
