On-Orbit Servicing (OOS) Architectures

On-Orbit Servicing (OOS) Architectures

OOS presents new opportunities for refueling, inspection, repair, maintenance, and upgrade of spacecraft (s/c). OOS is a significant area of need for future space growth, largely due to the increased congestion in space.

It will become very important to enable the servicing of low-earth orbit (LEO) s/c as the industry shifts its focus towards LEO. Our research looks into the tradespace of design variables for an overall system architecture for OOS in LEO constellations.
