Guided Net Intercept Vehicle for Active Debris Removal of Large Uncooperative Debris

View Video Presentation: https://doi.org/10.2514/6.2023-1297.vid The debris environment poses a growing threat to operational satellites, which has driven an interest in the development of active debris removal technologies. Removal of large pieces of debris on orbit is a key element to stabilizing this environment. Rocket bodies, in particular, have been found to have a high probability of fragmentation, and the removal of just five of them a year would stabilize the debris environment. Unfortunately, these rocket bodies are often tumbling, making them particularly difficult to approach and remove. A novel small satellite-guided net intercept vehicle concept is presented, which aims to allow for assured capture of uncooperative large debris targets on orbit. The system is composed of a storage unit, which houses the net and drag sail, and four identical maneuvering units, which control the net during capture and actuate a drawstring system to close the net. These deorbit kits are designed to be able to be dropped off in close proximity to a target and handle the detection and capture independently, though they can integrate information from outside sources. Key trades associated with rotating debris, closure mechanisms, and drag devices are discussed, along with the sizing of select components. The program will continue to develop key systems identified and reach a system requirements review by 2023.
