Abstract(in English)	We discuss the use of a monitoring camera on board a satellite to detect unknown satellites coming so close as to cause collision risk. Assuming that a camera on board our satellite tracks direction angles of an unknown target satellite, we try simulations of determining the target's trajectory. Simulations show that we cannot determine uniquely the target's trajectory, while we can decide whether we need a collision avoidance maneuver and can determine its strategy when we need it. The on-board camera does not need precise alignment, as the bias in direction angles can be estimated as an unknown parameter.
