NASDA has developed a micro satellite named ``μ-LABSAT'' on which University of Tokyo is planning to perform target motion estimation and target tracking experiments together with NASDA, Communication Research Laboratory (CRL) and National Aerospace Laboratory (NAL). The technology important for the mission success is the target release mechanism, which should release the target with a specified relative velocity and direction. Micro gravity and vacuum experiment has been performed to verify the design of this mechanism as well as to determine a certain design parameter. The paper describes this satellite project, the planned on-orbit experiment, outline of the micro-gravity experiment, and the results.
