 Abstract
In this paper, a disposal maneuver which complies the space debris mitigation guideline was analysed for KOMPSAT-2 as an example of LEO satellite. Definition of disposal altitude which comply the '25 year rule', re-entry survivability analysis of KOMPSAT-2 parts inside and casualty area analysis were performed using STK and ESA's DRAMA. Finally, assuming that there were several survival objects during uncontrolled re-entry stage, the re-entry initial orbit elements which show the low casualty probability were found even if there were various uncertainties about the initial orbit. As a result, KOMPSAT-2 should be descended its altitude at least 43km or up to 105km to comply '25 year rule' and there were heavy or heat resistant survival objects which generated casualty area. And if RAAN of re-entry initial orbit was 129 degree, total casualty probability was lower than standard value of space debris mitigation guideline even if there were uncertainties about the initial orbit.
