This report addresses the need for communications to a variety of stakeholder communities to enable global progress in Space Traffic Management. The vision of safely coordinating the operations of satellite missions and constellations requires awareness and actions by organizations from government, commercial, academic, nonprofit and multilateral sectors. This work adapts a Systems Architecture method and Stakeholder Analysis to address specific questions related to communications for Space Traffic Management. The report finds that additional effort can be applied for Primary Stakeholders to have two-way dialog with Secondary and Tertiary Stakeholders to understand what the Needs and Desired Outcomes are for those groups and show the urgency of taking action on Space Traffic Management.
