Small satellite characterization technologies applied to orbital debris Original Research Article

There are challenges associated with optical observations of Earth-orbiting objects that are at, or near, the limit of detection using terrestrial space surveillance sensors. These challenges include observing small objects not just for statistical purposes, but also with enough frequency and accuracy to move them into satellite catalogs, to provide the capability to routinely observe and characterize smaller objects, and to develop the capability to observe the satellite positions with increased accuracy. Until recently, ground-based observers could easily have mistaken such small objects as debris. Given the current pace of small satellite development, it may not be much longer before operational spacecraft of even smaller size are launched. AMOS is currently developing techniques to observe and characterize these small spacecraft, and applying those techniques to orbital debris.
