The invention belongs to the field of spacecraft control, and relates to an electric thrust in-orbit pointing calibration and thrust calibration method only using angular momentum measurement. According to the method, the correction iteration process of ignition-measurement-orientation adjustment is continuously carried out, the center-of-mass coordinate, the thrust orientation deviation and the magnitude of the satellite can be estimated at the same time only by using angular momentum change information, the efficiency of on-orbit calibration of the electric thruster can be effectively improved, and the method can be applied to various satellites using the electric thruster with the adjustable direction.

    本发明属于航天器控制领域,涉及一种仅使用角动量测量的电推力在轨指向校准及推力标定方法。本发明通过连续进行“点火‑测量‑调整指向”的修正迭代过程,实现仅使用角动量变化信息即可同时估计卫星质心坐标、推力指向偏差和大小,能够有效提高电推力器在轨标定的效率,可应用于各类使用了方向可调节的电推力器的卫星。
