Business Context
Inter-satellite coordination can improve constellation scheduling, formation control, distributed sensing, routing, and autonomous decision-making. However, frequent coordination messages consume communications bandwidth, processing capacity, and electrical power. Large constellations can generate substantial internal traffic if every spacecraft continuously exchanges detailed state information.
Space TRIZ Resolution
Coordination should use hierarchical, event-driven, or locally relevant information exchange rather than continuous communication among all spacecraft. Satellites can share summarized state information and communicate additional detail only when decisions require it. Operational groups can also coordinate locally without involving the complete constellation.
Applicable TRIZ Principles
Principle 1 – Segmentation organizes constellation coordination into smaller functional groups.
Principle 2 – Taking Out removes unnecessary information from routine coordination traffic.
Principle 19 – Periodic Action exchanges detailed information only when operational conditions require it.
Expected Outcome
Strong constellation coordination
Lower communication overhead
Reduced onboard processing demand
Greater constellation scalability
Decision Indicators
Early indicators include:
Internal constellation traffic grows rapidly with satellite count.
Spacecraft exchange detailed state information regardless of relevance.
Coordination consumes significant communications capacity.
Every spacecraft requires information from the complete fleet.
Network congestion begins to limit distributed operations.
