Collision Avoidance vs Mission Continuity

Business Context

Collision-avoidance maneuvers protect spacecraft from conjunction risks and help maintain responsible orbital operations. However, maneuvers can interrupt observations, communications, formation geometry, or other mission activities. They also consume propellant and may create additional coordination requirements. Avoiding every potential conjunction aggressively can therefore reduce productive mission time and spacecraft lifetime.

Space TRIZ Resolution

Collision management should combine improved prediction, risk classification, coordinated maneuver planning, and minimum-disruption responses. Maneuvers can be scheduled around mission activities where sufficient warning exists, and small early corrections may replace larger late interventions. Constellation-level coordination can also prevent multiple spacecraft from responding independently to the same orbital situation.

Applicable TRIZ Principles

Principle 10 – Prior Action uses early conjunction information to enable smaller and less disruptive responses.

Principle 15 – Dynamics adjusts maneuver strategy according to collision probability and mission conditions.

Principle 23 – Feedback continuously updates decisions as orbital uncertainty decreases.

Expected Outcome

Reduced collision risk

Higher mission continuity

Lower avoidance-related propellant consumption

More efficient conjunction management

Decision Indicators

Early indicators include:

Conjunction events frequently interrupt productive operations.

Avoidance decisions are made before orbital uncertainty is sufficiently refined.

Late maneuvers require substantial trajectory changes.

Multiple constellation spacecraft respond without coordinated planning.

Collision avoidance consumes increasing propulsion resources.
