This invention relates to the field of satellite on-orbit measurement, control, and maintenance technology, and particularly to a method for identifying the jamming position angle of a two-dimensional turntable on an on-orbit satellite using current scanning. The technical solution includes a process for identifying the jamming position angle of a two-dimensional turntable on an on-orbit satellite using current scanning. This invention analyzes the current response characteristics of the turntable drive motor on the primary bus, reverse-engineers the physical location of the jamming point, and establishes a high-order nonlinear mapping relationship between the motor's energizing time and rotation angle position through a uniform rotation calibration experiment on the ground using a dynamic simulation platform highly consistent with the on-orbit state. This mathematical model is then solidified into the satellite's computer as a benchmark calculation formula, significantly improving the engineering capabilities for on-orbit fault diagnosis and maintenance support.
