M/OD risk assessment system and its applications

A risk assessment system named meteoroid & orbital debris risk assessment system (MODRAS) developed for assessing risks of the spacecraft under the meteoroid and debris environment (M/OD EM) is presented. The computing resolution of MODRAS has been verified by both the three generic spacecraft geometries of inter agency debris committee (IADC) and similar foreign software such as BUMPER, ESABASE, and MDPANTO. The results show that the system is fit well with the computing results of the foreign software. Typical applications of the system are also presented, including a manned spacecraft and a space shuttle.
