Definition

Orbit integration method that adds external celestial body gravity as perturbation acceleration to the central gravitational field.

Application Value

Based on its definition, this term has significant application value in cislunar space missions. For example, in orbit design, its characteristics can be leveraged for transfer trajectory optimization; in orbit maintenance, it enables precise orbital control; in navigation and orbit determination, it can improve state estimation accuracy; in mission planning, it assists in determining transfer timing and strategies. Specific engineering applications require comprehensive analysis considering mission constraints and orbital characteristics.
