The program GEO-EVOL is now being updated at Kyushu University. The purpose of GEO-EVOL is to estimate population in geo-stationary orbit and its vicinity in the future based on the present situation and projected space activities. Among the model parameters that appear in GEO-EVOL, we examine the ratio that describes how many fragments cross GEO altitude among the total number created. The fragment migration ratio was kept constant in GEO-EVOL but must be a function of breakup energy and altitude. The code that can treat the fragment migration ratio as the function of breakup energy and altitude was named GEODEEM (GEO space Debris Environment Evolution Model). Breakup numbers can be estimated in each altitude bin with known population, but breakup energy can vary. Then, we can describe the population growth with respect to the associated energy level. The current result of our simulation will be presented.
