Definition

A transfer orbit arc connecting two position vectors with solar and lunar gravitational perturbations taken into account. Unlike the classical Lambert problem, the departure velocity requires a correction beyond the two-body solution, obtained through linearized iteration. The analytical approximation used in this study avoids numerical integration, greatly improving computational speed.

Application Value

该方法在轨道转移设计中被用于分析转移通道和能量最优轨迹，为低能量转移方案提供理论支撑。
