Abstrakt

Satellite formation flying is an example of an autonomous distributed system that relies on complex coordinated mode transitions to accomplish its mission. While the technology promises significant economical and scientific benefits, it also poses a major verification challenge since testing the system on the ground is impossible. In this paper, we experiment with formal modelling and proof-based verification to derive mode logic for autonomous flight formation. We rely on refinement in Event-B and proof-based verification to create a detailed specification of the autonomic actions implementing the coordinated mode transitions. By decomposing system-level model, we derive the interfaces of the satellites and guarantee that their communication supports correct mode transitions despite unreliability of the communication channel. We argue that a formal systems approach advocated in this paper constitutes a solid basis for designing complex autonomic systems.
