Definition
The process of maintaining preset relative positions and attitudes among spacecraft during a formation flying mission through active control. After formation deployment, the keeping phase requires smaller but continuous control forces. Performance metrics include baseline relative error, positional errors on each axis, and energy consumption. Formation keeping near libration points faces challenges from nonlinear dynamics and long-term accumulated errors.
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。
