ISO 23705:2026 – Space Systems: Collision Avoidance for Orbiting Objects

Space systems — Identifying, evaluating and avoiding collisions between orbiting objects

As the number of active satellites, debris, and space missions increase, robust protocols for collision risk management in orbit are essential for long-term sustainability.

• Defines data requirements for collision assessment, including orbital elements, covariance, and cross-sectional area
• Identifies best-practice techniques for estimating collision probability and consequences
• Establishes documentation and exchange protocols among SSA systems, providers, and spacecraft operators (e.g., CDMs—Conjunction Data Messages; adoption of ISO 26900, ISO 19389 data formats)
• Governs notification and reporting of upcoming conjunctions, with systemic procedures for operator response and maneuver execution

Applicability

Technical Insights

Common Technical Requirements

Across these standards, some shared themes and best practices emerge:

• Meticulous Measurement & Validation: All three standards emphasize robust measurement (whether dimensions, vibration, or risk probability) using harmonized methods and validated equipment.
• Quality Assurance Protocols: From connector qualification to the authenticity of orbital data, sustained QA is essential. Ongoing inspection, verification, and control are mandated at multiple lifecycle stages.
• Documentation & Traceability: Each standard requires clear, accessible documentation for critical processes—a must for regulatory audits, technical reviews, and investigations.
• Data Interoperability: Especially for space operations, standards adoption facilitates real-time, cross-organization exchange of safety-related data.

Best Practices for Implementation

1. Gap Assessment: Compare your existing processes and products versus new standard clauses—identify what must be modified.
2. Training and Communication: Equip engineering, QA, and operational staff with updated requirements. Make all documentation accessible and current.
3. Process Integration: Update your internal control plans, procurement specs, and R&D deliverables to reference current standard versions.
4. Supplier Engagement: Collaborate upstream to ensure all materials and components comply with new specs, especially for connectors and contact finishes.
5. Testing and Certification: Engage accredited labs for re-verification or certification. Document results and declarations per standard guidance.

Testing and Certification Considerations

• For connectors, follow EN and ISO test methods (EN 2591, EN 3197) and maintain qualification per revised protocols
• For GSE vibration, use calibrated instrumentation and reproduce specified test environments (track, speed, environmental factors)
• For space collision avoidance, maintain robust data exchange platforms, confirm coverage, and stress-test operational concepts with real-world scenarios
