Hypergol Refueling Tool (HRT) and Quick Disconnect (QD) System

About this technology

Overview

A non-cooperative satellite is a satellite that was not designed with on-orbit servicing in mind. Compared to a cooperative servicing interface, non-cooperative interfaces pose unique difficulties and challenges. Refueling is important to resupply of propellant and required pressurants or other media that allow a satellite with depleted fuel stores to extend its life. A potential, and likely, end-of-life event for a satellite is the depletion of propellant. Historically, satellites whose hardware and software components are still functioning properly will be decommissioned or de-orbited because the lack of onboard propellant does not permit proper spacecraft attitude and navigational control. The HRT and QD System can service non-cooperative satellites, addressing the challenges presented by noncooperative interfaces in order to access, interface, and manipulate non-cooperative assets.
