Moon: truncated Meeus/ELP analytic series (~0.3°). Sun: low-precision solar ephemeris. Cislunar & Lagrange-point spacecraft are SEEDED analytic approximations — plausible geometry and scale, deterministic phases — NOT live SPICE data. Not for operational use.
The live CelesTrak fetch failed and no cached catalog, local snapshot, or prior data was found. Note: CelesTrak blocks repeat downloads of the same file within ~2 hours — if you were just rate-limited, waiting is the fix, and RETRY will extend the block. Recommended: run orca_satcat_prep.py in this folder (writes active.tle), then reload. Or download manually:
