IDEA: In-situ Debris Environmental Awareness (original) (raw)

Abstract

This paper introduces IDEA the project for in-situ debris environmental awareness. The environment of micro debris, whose size is below 1 cm, has not been continuously monitored in any spatial region by common ground-based sensors due to their small dimension. The lack of the environmental awareness also results in the significant difference between the two widely used debris environment models: the one is ORDEM developed by NASA and the other is MASTER developed by ESA. The IDEA project aims to monitor the environment of micro debris at congested orbital altitudes to identify the accuracy of those models, and to provide practical information for the satellites at the same altitude region. This paper introduces and evaluates the concept of proposed monitoring missions.
