Dynamics of Satellite Disintegration.
Abstract
Satellite disintegration is examined in detail. Elements of the orbits of individual fragments, determined by DOD space-surveillance systems, are used to accurately determine the time and place of the fragmentation. Dual time-independent and time-dependent analyses are performed for simulated and real breakups. Methods of statistical mechanics are used to study the evolution of the fragment clouds by treating the fragments as an ensemble of noninteracting particles. A solution of Liouville's equation is obtained which enables the spatial density to be calculated as a function of position, time, and initial velocity distribution. Conversely, a relation is established between the observed fragment distribution and the time of fragmentation and initial velocity distribution. The probability of collision between a spacecraft and a fragment cloud is calculated.
