MODU Ghost-Satellite Catalogue — GNSS Doppler Residual Observations (frozen snapshot, 2026-10-10 to 2026-10-21)

907,675 per-epoch Doppler-residual observations of 103 GNSS satellites — GPS (32), GLONASS (24), BeiDou (31), Galileo (16) — collected 2026-10-10T03:03:49Z to 2026-10-21T06:29:31Z by a single consumer handset (Google Pixel 9) operating as a receive-only GNSS observer in West Kelowna, British Columbia, Canada (approx. 49.8°N, 119.6°W, 0.1° precision), and scored on a local workstation against SGP4 predictions from public CelesTrak TLEs. Each row is one satellite at one epoch: the Doppler the receiver measured, the Doppler the public orbit model predicted, the residual between them, the satellite's elevation, and the pipeline's verdict (CONSISTENT 766,402; LOW_ELEVATION 121,811; STALE_TLE 13,463; NEEDS_INVESTIGATION 4,651; GHOST_CANDIDATE 1,323 across 36 NORAD ids; NEEDS_OBSERVATION 25). GHOST_CANDIDATE is a pipeline flag for investigation, not a claim of an uncatalogued object. Collection stopped on 2026-10-17 when the observing handset went dark and resumed on 2026-10-20; 2026-10-18 and 2026-10-19 contain zero epochs (collection outage, disclosed). All v1.0.0-era rows are carried unchanged — per-day counts through 2026-10-17 are identical in both snapshots. 226,154 rows (24.9%) were backfilled and carry run-time timestamps; every such row is flagged in its notes field. The dataset files in this deposit are byte-identical to GitHub release v1.1.0 of J2theN1/modu-ghost-catalogue (see related identifier). Full schema, verdict glossary and methods are in the deposited README.md and METHODS.md.
