Definition
A set of quasi-orbital elements for trajectory design. Based on variants of equinoctial orbital elements, they provide an analytical framework for three-dimensional low-thrust trajectory design, avoiding the singularity issues of classical orbital elements at small eccentricities or inclinations.
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.
