Business Context
Frequent maneuvers can improve coverage, collision avoidance, formation control, or responsiveness to changing mission objectives. However, repeated trajectory changes increase orbit-determination workload and can reduce predictability for ground systems, partner spacecraft, and space traffic coordination. Maintaining highly predictable trajectories simplifies operations but limits maneuver flexibility.
Space TRIZ Resolution
Maneuver flexibility should be supported by rapid trajectory updating and standardized information exchange rather than by avoiding necessary movement. Planned maneuver windows, onboard navigation, automated orbit determination, and timely dissemination of updated orbital states can preserve predictability even when spacecraft maneuver frequently.
Applicable TRIZ Principles
Principle 10 – Prior Action defines maneuver opportunities and coordination processes in advance.
Principle 15 – Dynamics allows orbital behavior to change while continuously updating operational models.
Principle 23 – Feedback incorporates post-maneuver navigation data rapidly into trajectory predictions.
Expected Outcome
Greater orbital flexibility
Improved trajectory awareness
Reduced coordination uncertainty
More reliable post-maneuver operations
Decision Indicators
Early indicators include:
Maneuvers create prolonged uncertainty in predicted spacecraft position.
Operational teams avoid useful maneuvers because orbit updates are slow.
External coordination data becomes outdated after trajectory changes.
Orbit determination requires extensive manual processing.
Post-maneuver uncertainty disrupts subsequent mission activities.
