Definition

A real-time guidance algorithm embedding Lambert problem solutions into the powered flight phase: at each integration step, solve the Lambert problem from current state to target to determine required velocity, then command thrust along the velocity deficit direction. Thrust terminates when the deficit falls below a threshold, followed by ballistic flight.

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。
