The invention relates to the technical field of space electric propulsion, in particular to an electric propulsion on-orbit test method under a synchronous orbit. Comprising the following steps: carrying out a non-thrust preprocessing item test before satellite point fixing; when the target initial work period reaches an ascending node ignition area and a descending node ignition area, first grid preprocessing and second grid preprocessing are carried out respectively; after the grid preprocessing is finished, based on the actual average thrust of the first grid preprocessing and the actual average thrust of the second grid preprocessing, respectively determining a first test duration of a first thrust vector pointing centroid test carried out by the satellite in the ascending node ignition area and a second test duration of a second thrust vector pointing centroid test carried out by the satellite in the descending node ignition area; and after the first thrust vector points to the mass center test/the second thrust vector points to the ascending node ignition area/descending node ignition area of the next work period, the first ignition test/the second ignition test is carried out. According to the scheme, the influence of test thrust on the track can be eliminated, and the test efficiency can be improved.
