| 摘要: |
| 提出了一种上面级适应初始轨道大偏差的轨道在线规划策略，在上面级初始轨道参数存在较大偏差情况下，通过轨道在线规划，将规划后的控制诸元上传至上面级，使得上面级按照新的轨道飞行，将卫星送入目标轨道或大幅减小卫星入轨偏差，减小上面级由于入轨偏差修正过程中燃料的消耗。该策略可以广泛应用在上面级直接入轨发射MEO、GEO卫星等典型中高轨任务中。 |

| Abstract: |
| This paper provides a strategy of upper-stage on-line trajectory planning to adapt initial large deviation. When there is deviation of the upper-stage initial injection orbit parameters, we can send the replaned control data to the upper-stage with the on-line trajectory planning. And the upper-stage can fly in a new optimized trajectory, so as to put the satellites into the target orbit precisely, or to decrease the deviation and fuel consumption of the maneuver. This strategy can be extensively used for direct orbit injection missions to the high medium-earth-orbit， such as MEO(medium earth orbit) and GEO(geostationary orbit). |
