KLNS V4 — Korean Lunar Navigation Constellation: simulation code, candidate-orbit catalogue, and evaluation logs

This deposit accompanies the manuscript "Korean Lunar Navigation Constellation with Stability-Filtered Optimisation" (Yoo, Jee, & Kim, 2026, submitted to Scientific Reports). It contains the MATLAB simulation source, the full 10,368-element candidate-orbit catalogue, the 7,504-element stability-filtered pool, the GA and random-search benchmark logs underlying Fig. 6, the 720-hour orbital element histories underlying Fig. 5, the gridded NVS / GDOP / availability arrays underlying Fig. 3 and Supplementary Figs. S1–S8, the LaTeX source of the Supplementary Information, and a JSON index of all simulation parameters. This version (1.1.0) additionally includes the MATLAB validation scripts and degree/order-16 gravity coefficients that reproduce the RK4 fixed-step convergence study (Supplementary Table S8) and the GRGM1200A degree/order-16 gravity-field validation (Supplementary Table S9), both added during peer review. See README.md for a complete file-to-figure mapping.
