Many space-based imaging methods are conducted using spacecraft based telescopes or cameras; these are usually two-dimensional still images and video. To accurately map and analyze resident space objects (RSOs) a three-dimensional (3D) approach must be taken.
Project Details
RSOs can be any space-borne object that can present a hazard to safe space operations, ranging from man-made satellites to space debris found in low earth orbit (LEO). 3D imaging of an RSO can provide the necessary information for obstruction avoidance, with the ultimate goal of helping to mitigate space debris accumulation, In addition, small celestial body exploration missions and space situational awareness missions, rely on accurate 3D imaging for proximity operations, rendezvous and docking or touchdown and landing. ARAPAIMA (Application for Resident Space Object Autonomous Proximity Analysis and Imaging) is an Embry-Riddle Aeronautical University proximity operations mission sponsored by the US Air Force Office of Scientific Research (AFOSR), the Air Force Research Laboratory (AFRL) and the Embry-Riddle Aeronautical University at Daytona Beach Office of Undergraduate Research. The mission's objective is to perform the in-orbit demonstration of autonomous proximity operations for visible, infrared and 3D imagining of RSOs from a nanosatellite platform, and by doing so, demonstrate the applicability of nanosatellite technology in the fields of space situation awareness, reduction of orbital debris and asteroid characterization. The satellite is completely student-built, through the Preliminary (AE 427) and Detail Design (AE 445) undergraduate courses.
