Reference Orbit

Author: Tianjiang Shuo

Definition

The baseline orbit along which constellation satellites are distributed. A constellation's coverage and positioning performance depend on the reference orbit type (e.g., NRHO, Halo, DRO) and parameters (e.g., perilune radius, orbital amplitude).

Application Value

The Reference Orbit plays a significant role in cislunar space mission design, analysis, and control. In orbital design, it can be leveraged for transfer trajectory optimization; in navigation and control, it improves mission execution precision and reliability; in system analysis, it facilitates deeper understanding of complex multi-body dynamical behavior, guiding mission planning and risk assessment.
