Definition
Targeting parameters in deep space trajectory design. The B-plane is a plane passing through the target body's center and perpendicular to the incoming hyperbolic asymptote. The B-vector is the projection of the asymptote onto this plane; its direction and length determine the flyby geometry. In practice, periapsis altitude and inclination constraints are mapped to B-plane parameters, and the transfer trajectory is solved iteratively via differential correction.
Application Value
This term has significant application value in cislunar space missions。In the orbital design phase, engineers use relevant theories for trajectory optimization；In navigation and orbit determination, it is used to improve measurement accuracy；In attitude control and orbit maintenance tasks, it ensures stable spacecraft operation。In practical applications, parameter optimization and algorithm adaptation can be combined with mission requirements to improve mission success rate and resource utilization efficiency。
