http: // Overview Working Group Charter Work Programme Membership SC13 Relevance

http: // Working Group Charter Standardization and Technical Guidance for: –Launch Site and Ground Support –On-Orbit Operations –Astrodynamics and Flight Dynamics Scope to include: –Safety –Processes –Sustainability of the Space Environment –Models, Simulations, and Supporting Analysis

http: // Significant Work Items N726Space systems — Relative motion analysis elements after LV/SC separation Space systems - Orbit determination and estimation - Process for describing techniques 16158Space systems - Avoiding collisions with orbiting objects 16159Space systems - Launch pad and integration site - Analysis of failures 16164Space systems - Disposal of satellites operating in or crossing Low Earth Orbit 16699Space systems — Disposal of orbital launch stages 26900Space systems - Orbit data messages 14620Space systems - Safety requirements - Part 2: Launch site operations 27852Space systems - Orbit lifetime estimation Space systems - Orbital debris, routes to compliance and management for debris mitigation

http: // Significant Standards Published Orbit Lifetime Determination and Estimation Reentry Safety and Control Disposal of Satellites from Geostationary Orbit Space Debris Management Measurement of Remaining Propellant Launch Site Safety: Pre, Post, and On Orbit Launch Site Failure Reporting AIAA Best Practices in Astrodynamics

http: // Major Issues Avoiding Collisions with Orbiting Objects –Continuing misunderstanding between SC13 and SC14 resulting in dismissal of most SC14 requirements –Resolution: SC 14 to proceed independently with requirements and best practices as normative requirements

http: // New Work Proposed Time Intervals and Time Scales for Space Operations. Conjunction Assessment Requirements Design and Operation Handbook for Spacecraft and Launch Vehicle in Orbital Debris Environment Guidelines for Small Satellite Operations

http: // Summary Work item collaboration between meetings improving but still not sufficient. Requirement that all positive votes include support commitment is preventing progress. Interaction with SC13 grows tenuous
