Active self-stabilization control method for attitude of spacecraft in orbit virtual field

The invention discloses a spacecraft attitude active self-stabilization control method for an orbit virtual field, and the method specifically comprises the following steps: extrapolating the position and speed of a spacecraft orbit through the GNSS data of a current spacecraft; calculating the space disturbance torque T of the spacecraft according to the extrapolated orbit position and speed of the spacecraft and the correlation constants of the spacecraft; judging whether the space disturbance torque T reaches a threshold value or not, and determining that the spacecraft needs to be subjected to active attitude adjustment; calculating a spacecraft attitude adjustment strategy through the space disturbance torque T; and controlling the spacecraft to carry out attitude adjustment at a specific moment according to the spacecraft attitude. According to the active self-stabilization control method for the attitude of the spacecraft, spacecraft control of attitude and orbit control is completed when no measuring
