As part of the work, we survey TLE orbit histories, estimate A/M from TLE histories, and compare them to debris environment models to assign sizes and masses. By surveying TLE histories, it is possible to determine orbital changes due to the termination of operations or PMD of individual satellites, as well as anomalous changes due to collisions, etc. and their timing. We have worked to automatically identify and classify whether a satellite is still under control or out of operation, and whether the orbit change is due to operational control, PMD, or a collision event, based on the characteristics that appear in TLE histories. We are considering incorporating machine learning methods to improve their accuracy.","subitem_description_type":"Other"}]},"item_4_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
