WITHDRAWN: HotSwap Component Exchange System for Space Applications

The HotSwap component exchange system is a standardized interface for modifying physical objects in space without the need to de-orbit or decommission the operating satellites. The system is comprised of a Host which is installed on the satellite, Cartridges which interface with payloads, and an End Effector which is used by an ISAM vehicle to execute exchanges. Similar in concept to a USB interface, the HotSwap project aims to provide a simple and customizable option for augmenting space assets. A major aspect of this approach includes creating a strong physical linkage between the servicing vehicle, Cartridges, and Host unit to prevent unexpected disconnects from tumbling or RPOD operations. Additionally, the Cartridge/Host approach allows for satellite parameters to be adjusted in situ, as Cartridges can provide voltage conversion, data protocol changes, or adjustments to the physical size/shape of the vehicle. Issues explored in development include achieving acceptable speed and accuracy for grappling, developing robotic systems, and integrating multiple different electronic components to work in tandem. Currently, the HotSwap system has reached TRL 3, having been developed and demonstrated through a USSF D2P2 SBIR and the SpaceWerx TRL Bootcamp managed by The Aerospace Corporation.
