Reentry Analysis and Risk Assessment for End-of-Life Disposal of a Multi-layer LEO Satellite

Reentry Analysis and Risk Assessment for End-of-Life Disposal of a Multi-layer LEO Satellite As the tasks of satellites become more complicated, the satellites become bigger, and various kinds of mission payloads are loaded inside them. To analyze the disposal of low Earth orbit satellites at the end of their useful life, a reentry analysis method that includes objects with several layers is proposed in this paper. For precise analysis, an object analysis list is used to simulate the process sequence between parent and child object when break-up occurs, and an information inheritance method on random transverse velocity generation is proposed. In consideration of the proposed method, reentry survivability analysis was performed, and the results were compared with the debris risk assessment and mitigation analysis reentry analysis program of the European Space Agency. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Aeronautical & Space Sciences Springer Journals

Abstract

As the tasks of satellites become more complicated, the satellites become bigger, and various kinds of mission payloads are loaded inside them. To analyze the disposal of low Earth orbit satellites at the end of their useful life, a reentry analysis method that includes objects with several layers is proposed in this paper. For precise analysis, an object analysis list is used to simulate the process sequence between parent and child object when break-up occurs, and an information inheritance method on random transverse velocity generation is proposed. In consideration of the proposed method, reentry survivability analysis was performed, and the results were compared with the debris risk assessment and mitigation analysis reentry analysis program of the European Space Agency.
