Intermediate Circular Orbit

Definition

A local circular orbit used in the backward integration method for segment-wise velocity correction. Since prolonged backward integration deviates from the approximate tangential direction due to lunar gravitational perturbation, the local circular orbit velocity is computed at each backward integration endpoint. Shooting method correction aligns the spacecraft velocity with the circular orbit, which then serves as the new starting point for continued optimization.

Application Value

This term在cislunar space missions中has important application value. In orbit design, it can be used foroptimizing transfer trajectories, reducing mission fuel consumption. In attitude control and dynamics analysis, it helps understandthe motion characteristics of spacecraft in complex gravitational fields, providing theoretical support for mission planning. In navigation and orbit determination, methods based on this termcan improve orbit prediction accuracy, supporting the development of autonomous navigation algorithms.
