Abstract:

Distributed spacecraft systems with enhanced formation flying (EFF) technology for onboard constellation and formation control will enable large numbers of spacecraft to be managed with a minimum of ground support. EFF facilitates a ?virtual platform? concept which lowers total mission risk, increases science data collection and adds considerable mission flexibility. The requirement to act as a unified information system places requirements on the system architecture that go above an beyond what is required for traditional systems. We propose a software based infrastructure that facilitates dependable formation and operation of distributed real-time control systems with several innovations that advance the state of the art in distributed systems technology and sensor webs. These innovations include: 1) cold start algorithms that allow for autonomous, dependable system organization and formation, 2) distributed on-line configuration control, monitoring and health assessment processes that operate in concert across the entire system allowing for coordinated system operation, 3) a multi-level scheduling approach that allows for distributed control elements to be responsive to local events and to participate in system wide coordinated operations and 4) a robust fault/error model that accounts for arbitrary fault/error cases and anomalies, thereby providing superior fault tolerance, particularly for Single event Upsets (SEUs).
