Query: On-Orbit Smart Camera System to Observe Illuminated and Unilluminated
  Space Objects   The wide availability of Commercial Off-The-Shelf (COTS) electronics that can
withstand Low Earth Orbit conditions has opened avenue for wide deployment of
CubeSats and small-satellites. CubeSats thanks to their low developmental and
launch costs offer new opportunities for rapidly demonstrating on-orbit
surveillance capabilities. In our earlier work, we proposed development of
SWIMSat (Space based Wide-angle Imaging of Meteors) a 3U CubeSat demonstrator
that is designed to observe illuminated objects entering the Earth's
atmosphere. The spacecraft would operate autonomously using a smart camera with
vision algorithms to detect, track and report of objects. Several CubeSats can
track an object in a coordinated fashion to pinpoint an object's trajectory. An
extension of this smart camera capability is to track unilluminated objects
utilizing capabilities we have been developing to track and navigate to Near
Earth Objects (NEOs). This extension enables detecting and tracking objects
that can't readily be detected by humans. The system maintains a dense star map
of the night sky and performs round the clock observations. Standard optical
flow algorithms are used to obtain trajectories of all moving objects in the
camera field of view. Through a process of elimination, certain stars maybe
occluded by a transiting unilluminated object which is then used to first
detect and obtain a trajectory of the object. Using multiple cameras observing
the event from different points of view, it may be possible then to triangulate
the position of the object in space and obtain its orbital trajectory. In this
work, the performance of our space object detection algorithm coupled with a
spacecraft guidance, navigation, and control system is demonstrated.
