The invention relates to a multi-stage on-satellite calibration device for increasing calibration speed, which comprises a black body, a controller, a temperature control element, a temperature sensor, a rope, a mounting plate, an angle fixing seat and a fixing cylinder on the mounting plate, a limiting block, a rubber mat, a motor and a transmission mechanism, and multiple layers. And the rope passes through the through holes in the four bosses of the black body and then is connected with the four corner fixing seats on the mounting plate. And the rope is finally wound on the fixed cylinder for dispensing and fixing after being tensioned. The four limiting blocks are fixed above the four bosses of the black body, the black body is limited between the limiting blocks and the mounting plate, the sides, facing the black body, of the limiting blocks and the mounting plate are each locally provided with a flexible gasket, and the temperature control element and the high-precision temperature sensor are pasted on
