Abstract: More and more electric propulsion (EP) systems have been used on spacecraft for orbit correction. The configuration, installation and usage modes of electric thruster determine the adjustment strategy of EP. In most cases, the satellite in orbit needs calibration and adjustment of the electric thrust vector. An algorithm to calibrate and adjust the electric thrust vector of a certain type of GEO satellite using the change of angular momentum was presented, as well as an application case of this algorithm in orbit for the first time in China. The result of inorbit calibration suggests that the algorithm is correct and practical, providing a solution for the calibration and adjustment of EP on satellite.
