Cost Efficiency Analysis of Space Debris Removal from Geostationary Orbit Using Service Spacecraft

摘要

An economic efficiency model of spacecraft is developed. Besides, such economic efficiency indicators as profitability index and payback period of a project are designed. This model is modified to calculate the economic efficiency of a service spacecraft and as a result an overall index of project efficiency is developed on its basis. This index results in minimized interruptions when the system point is used in the geostationary orbit. The analysis of conditions for the effective use of service spacecraft aimed at the removal of space debris from the geostationary orbit is carried out; the recommendations on its operating performance are made.
