A satellite breakup can cause collision risk to other resident satellites. If the time, location, and energy content of the breakup can be determined, The Aerospace Corporation has models that can quickly estimate the risk to other resident satellites from the debris. We have developed a method that allows determination of all required breakup parameters within about 12 hours after the breakup event. If a large number of radar tracks are available, this timeline could be even shorter. The method then facilitates rapid determination of debris collision risk to resident satellites, providing satellite operators with timely space situational awareness.
