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。
This paper presents an on-orbit on-line planning strategy to adapt to the large initial trajectory deviation. When there is a large deviation in the initial orbital parameters of the upper level, the planned control elements are uploaded to the upper level through the on-orbit planning, In accordance with the new orbit, the satellite into the target or substantially reduce the satellite orbit into orbit, to reduce the upper level due to the track deviation correction fuel consumption. This strategy can be widely used in the typical high-orbit missions such as MEO and GEO satellites launched directly into the upper level.
