Analysis of the effectiveness of space debris mitigation measures using the delta model Original Research Article

Firstly, the paper outlines the different space debris mitigation measures proposed or in use by the national space agencies in order to reduce and stabilise the predicted long-term growth of the space object population. The rationale for analysing the effectiveness of these different mitigation techniques with space debris models is introduced. Then, the features of Debris Environment Long Term Analysis (DELTA) model are described. Special attention is given to the DELTA model approach for the detailed simulation of realistic mitigation measure scenarios. The model predictions of long-term debris environment evolution for these scenarios are then analysed and discussed in terms of their relative efficiency in reducing the debris population and the consequences for the collision risks in key operational orbits.
