Definition

The angle between the arrival impulse velocity vector and the local velocity vector on the DRO. Positive when counterclockwise, negative when clockwise.

Application Value

In orbit design and optimization, this concept is used to analyze spacecraft motion characteristics in the cislunar multi-body gravitational field, providing a theoretical basis for low-energy transfer trajectory design.
