Lunar High-Latitude Region

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

Lunar regions at high absolute latitude (typically near the poles), where traditional near-circular lunar orbit coverage is weakest and positioning accuracy is poorest. NRHO orbits, due to their large out-of-plane amplitude, provide superior coverage of these regions compared to Halo orbits and near-circular lunar orbits.

Application Value

These coefficients form an important tool in lunar theory, essential for high-precision orbit calculations in lunar missions.
