The invention relates to a satellite-borne magnetic torquer for digitally adjusting a magnetic moment value. The satellite-borne magnetic torquer comprises a magnetic assembly control unit, a temperature sensor and a three-axis magnetic torquer, the temperature sensor and three magnetic moment coils of the three-axis magnetic moment device are electrically connected with the magnetic assembly control unit. The magnetic assembly control unit is further electrically connected with a spaceborne computer and receives a target magnetic moment instruction control signal from the spaceborne computer. The magnetic assembly control unit generates a driving signal for controlling the magnitude and direction of current in each magnetic moment coil according to the target magnetic moment instruction control signal; a temperature value measured by the temperature sensor and a magnetic moment feedback value of each magnetic moment coil are collected in real time; and through temperature compensation and magnetic moment control, generating a magnetic moment value corresponding to the target magnetic moment instruction control signal in each magnetic moment coil, and adjusting the attitude of the satellite. According to the invention, the satellite attitude adjustment precision is higher, the attitude adjustment is more stable, and the workload of a spaceborne computer is saved.
