The Orbital Express Capture System (OECS) is one of the key technologies successfully demonstrated as part of the
Orbital Express Demonstration System flight operations that took place between March and July, 2007. The OECS
supported all demate, capture and berthing activities throughout the span of on-orbit activities, with no anomalies. This
paper will briefly review the Orbital Express (OE) program, including goals, key milestones & events and other major
subsystems particularly relevant to the OECS performance. A summary of the major activities in the Virtual System
Integration process, as applied to the OECS, to ultimately verify satisfactory pre-flight performance, will be presented.
Finally, actual on-orbit performance of the OECS will be described.
