The invention relates to the field of satellite mechanisms, in particular to a satellite deorbit device. The satellite deorbit device comprises a bottom plate, side cover plates, a power source assembly, a driven assembly, a sail truss mechanism and a locking mechanism, the peripheral area of the bottom plate is rotationally connected with the side cover plates, the power source assembly and the driven assembly in transmission connection with the power source assembly are arranged in the central area, the driven assembly is in sliding connection with one end of the locking mechanism, and the other end of the locking mechanism is connected with the side cover plates in a clamped mode; a containing space is formed by the bottom plate and the side cover plates, a sail unfolding film capable of being unfolded is arranged in the containing space, the corners of the sail unfolding film are fixedly connected with the extending end of the sail truss mechanism, and the sail truss mechanism is connected with the driven assembly and driven by the driven assembly to extend out. According to the satellite deorbit device, the power source assembly can be controlled through the control signal, and the sail unfolding process of the satellite deorbit device is controlled; the unfolding success rate of the deorbit sail is improved, and the satellite hang time is shortened.
