SPACE DEBRIS COLLISION PREDICTION RESEARCH

The population of orbital debris is increasing and these debris has serious hazards to spacecrafts in the earth orbit so to form an impact to human’s space activities. In recent decades, researches on space debris and its applications have attracted more and more attentions as a branch of space environmental study. In this paper, the issue of Space Debris Collision Prediction key techniques were studied, there after, the prediction method was established and tested. With large numbers of debris orbital data collected, this method and codes were verified by two collision and avoidance examples so to prove their validity. The conclusion was deduced that developing the collision avoidance technique and applying it into practice is feasible.
