Orbital Debris is the collection of defunct human-made objects in earth orbit, such as old satellites, spent rocket stages, and fragments from disintegration, erosion, and collisions – including those caused by the space debris itself. As of December 2016, five satellite collisions have resulted in generating space waste (read more).
Orbital Debris is a matter of growing interest for the scientific community in the space field. Hazards directly linked to it (i.e. Kessler Syndrome) are serious threats for the future of space missions. Ad-hoc procedures for next generation satellites and launchers are being adopted to avoid proliferation of space junk, but mitigation strategies to handle the current situation (> 750’000 objects tracked today) are needed too.
Nurjana Technologies presents an extension of current proprietary tracking algorithm which applies Data Fusion techniques and Kalman filtering on noisy Radar/Optical measures for accurate trajectography. Currently on duty in numerous Missile Test Range around the globe, it has been generalized to effectively track space debris in LEO under the action of typical perturbations. Case studies are presented to demonstrate possible applications and accuracy estimation.
