The invention discloses a method and device for controlling constellation satellite deorbit, electronic equipment, a medium and a product. The method comprises the steps that current orbit parameters and target orbit parameters of a constellation satellite are obtained, the current orbit parameters comprise the current semi-major axis and the current eccentricity rate of a current orbit, and the target orbit parameters comprise the target semi-major axis and the target eccentricity rate of a target orbit; based on the current orbit parameter, the target orbit parameter, the semi-major axis weight and the eccentricity ratio weight, constructing a target function about the deorbit direction of the constellation satellite; the semi-major axis weight and/or eccentricity weight in the target function are/is adjusted at a plurality of discrete nodes where the constellation satellites deorbit, the target deorbit direction of the constellation satellites at each discrete node is obtained, and the target deorbit direction is a track enabling the deorbit duration of the constellation satellites to be shortest; and controlling the constellation satellite to deorbit along the target deorbit direction. According to the scheme provided by the invention, the complexity of calculating the satellite deorbit trajectory can be reduced, so that the deorbit efficiency of the satellite is improved.
