The inventio provides a ground test stand for simulating reuse of a small space satellite. The ground test stand includes an active end and a passive end that can be docked and separated. The dockingand separation of the active end and the passive end are realized through a first docking mechanism interface and a second docking mechanism interface. The connection of a charging active apparatus and a charging passive apparatus is realized while docking through the connection of a first electric connector interface and a second electric connector interface, and the connection of a propellant supplementing apparatus and a propellant supplemented apparatus is realized while docking through the connection of a first supplement interface and a second supplement interface. A control device generates docking instructions, supplement instructions and charging instructions to respectively control the docking, propellant supplement and charging of the passive end by the active end. The ground test stand for simulating reuse of a small space satellite can verify docking, propellant supplement and charging process integrated design technologies.
