Abstract
Orbital debris modeling at Kyushu University was initiated with satellite impact testing, aiming to investigate low-velocity impact phenomena possible in the geosynchronous Earth orbit. Testing results were incorporated in an orbital debris evolutionary model for the geosynchronous Earth orbit region, named GEODEEM. Kyushu University also has developed an orbital debris evolutionary model for the low Earth orbit, named LEODEEM. The orbital debris evolutionary models are an essential tool to predict the future orbital debris environment and to discuss on what and how to do for orbital debris mitigation. This paper will briefly introduce orbital debris modeling being conducted at Kyushu University.
