Systems Engineering Framework for In-Orbit Refuelling
In-Orbit Refuelling (IOR) Architectural Initiative What Is This Project The IOR Architectural Initiative is an eight-week systems engineering project created to deliver a structured architectural decomposition of an In-Orbit Refueling (IOR) system. Phase I applies a disciplined systems engineering process to define mission context, capture requirements, and develop a coherent system architecture. The initiative is […]
In-Orbit Refuelling
In orbit refueling (IOR) is the capability to transfer propellant to a spacecraft after it has been launched and placed into orbit. Source – Space.Com Propellant is one of the most critical life-limiting resources of any spacecraft. It enables: Orbit insertion and transfer Station-keeping and attitude control Collision avoidance maneuvers Mission extension and repositioning Controlled […]
