AbstractSpace debris smaller than 1 mm in size still have enough energy to cause a fatal damage on a spacecraft, but such tiny debris cannot be followed or tracked from the ground. Therefore, knowledge on sub-millimeter-size debris should be incorporated in design of spacecraft to minimize the damage due to such tiny debris. IDEA the project for In-situ Debris Environmental Awareness, which aims to detect sub-millimeter-size debris using a group of micro satellites, has been initiated at Kyushu University. This paper proposes data assimilation method for estimating sub-millimeter-size debris environment using in-situ measurement data. The proposed method uses particle filter that is one of the data assimilation methods applicable to nonlinear system. This paper also estimates the environment from virtual in-situ measurement data to verify the proposed method. The verification demonstrates that the proposed method can estimate the distribution and number of debris approximately.
