Definition

A dynamical model that includes all relevant perturbation sources in orbital motion simulations. The high-fidelity model in this work incorporates the lunar gravitational potential (with LP100K high-degree harmonics) and third-body gravitational effects of Earth and Sun, offering far greater accuracy than the CR3BP.

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。
