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.

    本发明涉及空间电推进技术领域,特别涉及一种同步轨道下电推进在轨测试方法。包括:在卫星定点前进行无推力预处理项目测试;在目标起始工作周期到达升交点点火区和降交点点火区时,分别进行第一栅极预处理和第二栅极预处理;栅极预处理结束后,基于第一栅极预处理和第二栅极预处理的实际平均推力,分别确定卫星在升交点点火区进行的第一推力矢量指向质心测试的第一测试时长和在降交点点火区进行的第二推力矢量指向质心测试的第二测试时长;直至第一推力矢量指向质心测试/第二推力矢量指向质心测试完成后的下一个工作周期的升交点点火区/降交点点火区进行第一点火测试/第二点火测试。本方案可以消除测试推力对轨道的影响,可以提高测试效率。
