A Q-GERT model was developed to simulate the satellite environment, including the untracked man-made population, and to calculate a probability of collison for any satellite of interest. Provision for launches, explosions, collisions including ASAT, retrieval, reposition, and decay was made. The model is structured to easily vary the rates at which these activities occur and to observe changes in the satellite population through which a satellite of interest must travel. Variance of the rates, and the resultant change in probability of collision allows evaluation of satellite population management alternatives such as reducing launch rates or increasing retrieval of spent, but still capable of exploding, satellites. The model is proposed for use by both the USAF SPACE COMMAND and NASA.
