Abstract
This paper conducts an economical evaluation of the geosynchronous Earth orbit (GEO) under different proposed mitigation measures, including new legal standards, such as a lower satellite explosion rate and restrictions on the number of launches. The computer model, GEO-EVOL<sup>1 and 2</sup>, was used to run different mitigation scenarios. The simulation result shows that the re-orbit maneuvering and the restriction of satellite explosions to the rate of 4*10<sup>-6</sup> are one of the most cost effective measures and indispensable for a sustainable GEO environment over the long term. As for the economical valuation, the lower discount rate ( less than or equal 6%) should be used to correspond with the increasing... (More)
This paper conducts an economical evaluation of the geosynchronous Earth orbit (GEO) under different proposed mitigation measures, including new legal standards, such as a lower satellite explosion rate and restrictions on the number of launches. The computer model, GEO-EVOL<sup>1 and 2</sup>, was used to run different mitigation scenarios. The simulation result shows that the re-orbit maneuvering and the restriction of satellite explosions to the rate of 4*10<sup>-6</sup> are one of the most cost effective measures and indispensable for a sustainable GEO environment over the long term. As for the economical valuation, the lower discount rate ( less than or equal 6%) should be used to correspond with the increasing threats of space debris in the GEO environment, where they have no natural forces to help remove the debris. New international regulations or agreements on debris mitigation are necessary to help ensure the long-term economic benefits from the space activities in the GEO region, however this will not be an easy path. Possible steps to reach a long-term sustainable GEO environment from the given results of this study are also discussed. Copyright (Less)
