摘要

The Debris Environment Long Term Analysis (DELTA) model, upgraded at QinetiQ for the European Space Agency (ESA), now has the capability to simultaneously model the future evolution of the space debris environment in both low and high Earth orbit. This allows a first, detailed analysis of the evolution of space debris in high Earth orbit using DELTA, focusing on the growth of the environment in the geosynchronous region. The effectiveness of proposed mitigation measures in preserving this orbital region is investigated. It is found that the combination of mission-related object limitation, passivation, solid rocket motor slag reduction and re-orbiting of satellites and rocket bodies at the end of their useful life, is successful in stabilising the geostationary ring for the next century. The IADC (Inter-Agency Space Debris Coordination Committee) re-orbit guideline is modelled and it is concluded that for this guideline to be effective in removing mass from the operational region, the eccentricity of re-orbited satellites and rocket bodies must be kept as small as possible.
