Space Mission Systems Engineering Training by Tonex
The Space Mission Systems Engineering Training provides a practical, end-to-end understanding of how space missions are conceived, analyzed, architected, designed, integrated, verified, validated, operated, and sustained.
The program applies systems engineering principles to the complete space mission, including the space segment, payload, spacecraft bus, launch segment, ground segment, communications architecture, mission operations, and supporting enterprise systems.
Participants work from mission objectives and stakeholder needs through CONOPS, requirements, functional analysis, architecture, trade studies, interfaces, technical budgets, risk management, verification and validation, and mission readiness.
The training is organized as four 4-hour sessions, allowing participants to progressively develop a simplified space mission through exercises and workshops.
