AI Technical Summary
Technical Problem
Existing technologies suffer from orbital deviations during satellite transfer to long-distance retrograde orbits, resulting in low orbital accuracy and high fuel consumption.
Method used
By combining the orbital B plane and characteristic correction points at the perigee, the nominal orbit of the transfer orbit is reconstructed. The orbit is then corrected using the position difference and the correction velocity increment to ensure that the satellite accurately enters the long-distance retrograde orbit.
Benefits of technology
This improved the orbit insertion accuracy of satellites transferred to long-distance retrograde orbits, while reducing the fuel consumption required for orbit correction.

Abstract
本发明提供了一种远距离逆行轨道的转移轨道修正方法、装置和电子设备，方法包括：根据第一位置差值确定目标标称轨道；其中第一位置差值为由星箭分离实测轨道参数推算的第一预报位置与初始标称轨道对应位置的偏差值；第一预报位置包括近月点，在近月点，第一位置差值由预报轨道B平面与初始标称轨道B平面确定；在当前修正点，预报卫星在下一个修正点时的第二预报位置，并根据第二预报位置得出预报轨道与目标标称轨道的第二位置差值；根据第二位置差值求取当前修正点所需的第二修正速度增量；根据第二修正速度增量对卫星的运行轨道进行修正。本发明能够消除转移轨道中途转移偏差，确保卫星顺利转移至DRO轨道，轨道修正燃料消耗也更低。
