Abstract
An emergency deorbit device provided in a satellite flying on an orbit around the earth includes a propulsion module generating thrust for separating the satellite from the orbit, a reception unit receiving a repeat signal repeatedly sent at an interval from an sending unit of a satellite bus in the satellite, a detection unit outputting a detection signal when the reception unit does not receive the repeat signal in a set time period or when the reception unit receives a deorbit command from the sending unit or from an outside of the satellite, an activation device performing, in response to the detection signal, processing for activating the propulsion module, and a power supply device provided separately from a power supply device of the satellite bus and supplying electric power to the reception unit, the detection unit, and the activation device.
