Next in the Launch Queue : Raven
Raven will perch on an outside platform of the International Space Station to demonstrate elements of the real-time, relative navigation technology that would be needed for such a system. As vehicles approach and depart from the space station, Raven will track them in action and send the data it collects to Earth. NASA operators will then evaluate how Raven's technologies work as a system and adjust the system to increase Raven's tracking performance.
