This paper briefly introduces IDEA the project for In-situ Debris Environmental Awareness, aiming a prompt and clear understanding of the current submillimeter-size debris environment in the low Earth orbit region. Orbital debris, even smaller than 1 mm, may cause a fatal damage on a spacecraft. Therefore, knowledge on submillimeter-size debris should be incorporated in design of spacecraft. However, the current submillimeter-size debris environment has not been defined well because measurements are quite limited in terms of orbital regimes and not continuously available yet. Thus, the IDEA project proposes to deploy a group of micro satellites, which conduct in-situ and near real-time measurements of submillimeter-size debris, into any orbital regimes to be monitored. This paper also introduces a simple constraint equation applicable for orbital planes on which debris contribute to the collision flux that a measurement satellite may experience. Finally, this paper reveals that two measurement satellites or more are necessary to properly estimate the orbital parameters of a broken-up object.
