The invention relates to a carrying satellite power-on and power-off circuit and method. The circuit comprises a power-on control circuit, a satellite catalogue electric connector, a storage battery pack and a relay. The negative end of the storage battery pack is connected with the negative input end of the power-up control circuit through the relay, the positive end is connected with the positive input end of the power-up control circuit, and the output end of the power-up control circuit is connected with the positive end of the solar cell array BUS + power supply main bus; during a ground test, the relay is closed, and the power-up control circuit controls the storage battery pack to power up the satellite; one end of the relay is connected with the star catalogue electric connector first connection point, the other end is connected with the star catalogue electric connector second connection point, and the first connection point and the second connection point are short-circuited in a transmitting state; the power-up control circuit disconnects the storage battery pack from the satellite before the satellite and the rocket are separated in a launching state; and after the satellite and the rocket are separated, the storage battery pack is controlled to power up the satellite. Ground rapid testing can be achieved, the requirement for reliable power-up of the small satellite after the small satellite is launched in the whole-satellite power-off state can be met, the size is small, and the weight is light.
