# RPO replay: Cosmos 2612 → ICEYE-X36 (Sep 30 – Oct 21, 2026)
|
||||
|
||||
A 45-second, physics-grounded reconstruction of the Russian military satellite
|
||||
Cosmos 2612 (NORAD 68762) maneuvering to within a few hundred meters of the
|
||||
U.S.-registered ICEYE-X36 SAR satellite (NORAD 59103), rendered in CesiumJS
|
||||
over Esri World Imagery and exported as 16:9 and 9:16 video.
|
||||
|
||||
```sh
|
||||
python3 tools/rpo-replay/model.py # orbit reconstruction -> data.json
|
||||
python3 tools/rpo-replay/build_models.py # procedural GLBs
|
||||
node tools/rpo-replay/render.mjs --format 16x9 --stills 2,24,32 # spot checks
|
||||
node tools/rpo-replay/render.mjs --format 16x9 # all frames (resumable)
|
||||
node tools/rpo-replay/render.mjs --format 16x9 --encode # -> MP4
|
||||
```
|
||||
|
||||
Formats: `16x9` (1920×1080), `9x16` (1080×1920), and `preview` / `preview-v`
|
||||
at half size. Output goes to `output/rpo-replay/<format>/`. Requires
|
||||
`pip install sgp4 numpy scipy pillow`, Playwright's Chromium (SwiftShader, no
|
||||
GPU), and ffmpeg.
|
||||
|
||||
## What is measured and what is modeled
|
||||
|
||||
**ICEYE-X36** is propagated with SGP4 from its public CelesTrak element set
|
||||
(`tles.txt`). X36 did not maneuver in this window.
|
||||
|
||||
**Cosmos 2612** has no public element-set history without an account, so its
|
||||
path is a relative-orbit reconstruction about X36:
|
||||
|
||||
- Quasi-nonsingular relative orbital elements (δa, δλ, δe, δi), advanced
|
||||
with Keplerian along-track drift and the differential J2 node drift. The
|
||||
47 km "high park" is what swings Cosmos 2612's orbit plane into X36's.
|
||||
The model needs a 0.27° initial plane offset; published analysis gives
|
||||
~0.22°.
|
||||
- Burns are impulses through Gauss's variational equations. SMA changes are
|
||||
two half-orbit-apart tangential impulses. Each burn is timed inside the
|
||||
element-set window that KeepTrack, LeoLabs, and Marco Langbroek published.
|
||||
- Solved checkpoints:
|
||||
- Oct 12 overhead pass, then 480 km behind.
|
||||
- ~400 km on Oct 15.
|
||||
- 3 km behind after the Oct 16 braking burn.
|
||||
- 2.0 / 0.99 / 0.72 / 0.60 km on Oct 17.
|
||||
- 5.1 km behind and 140 m higher at 07:38 Oct 18.
|
||||
- 293 km on Oct 19.
|
||||
- Matched SMA, 477–479 km behind, from Oct 21. This matches today's Cosmos
|
||||
2612 element set.
|
||||
- The model gives ~60 m/s total Δv (KeepTrack estimates ~67 m/s). The
|
||||
closest approach comes out at **~325 m, 01:28 UTC Oct 18**, in Earth's
|
||||
shadow. Published estimates range 150–650 m. Langbroek gives ~01:35 UTC.
|
||||
|
||||
The 26 m and 25 m figures some outlets quoted come from element sets taken
|
||||
after the departure burn, and KeepTrack rejects them. This replay does not
|
||||
use them.
|
||||
|
||||
## Rendering conventions
|
||||
|
||||
- Camera and Earth ride with X36 on a slower "backdrop" clock during
|
||||
time-lapse to avoid strobing. Relative motion runs at the on-screen rate.
|
||||
Around closest approach the two clocks are identical, so lighting, shadow,
|
||||
and the following orbital sunrise are true to time.
|
||||
- Up close, the spacecraft are drawn enlarged (the factor is on screen, capped
|
||||
at 150×). At closest approach they are at true scale.
|
||||
- In Earth's shadow the models get a dim blue fill so their shapes stay
|
||||
readable.
|
||||
- ICEYE-X36 is modeled to ICEYE's published Gen-3 dimensions: 3.2 × 0.4 m
|
||||
antenna, ~3.25 m span. No public imagery of Cosmos 2612's design exists, so
|
||||
its model is illustrative.
|
||||

||||

"""Reconstruct the Cosmos 2612 / ICEYE-X36 rendezvous (Sep 30 - Oct 22, 2026).
|
||||
|
||||
ICEYE-X36 is propagated with SGP4 from its public CelesTrak element set.
|
||||
Cosmos 2612 is carried as quasi-nonsingular relative orbital elements (ROE)
|
||||
about X36 and advanced with linearised Keplerian drift plus the differential
|
||||
J2 node drift. Manoeuvres are tangential / normal impulses applied through
|
||||
Gauss's variational equations, timed inside the element-set windows that
|
||||
KeepTrack, LeoLabs and Marco Langbroek published. The final state is pinned
|
||||
to Cosmos 2612's own current element set (479 km behind, matched SMA).

"""Data-driven reconstruction of the Cosmos 2612 / ICEYE-X36 encounter (v4).
|
||||
|

Inputs: the public element-set history in tle/ (Space-Track catalog via the
|
||||
OMPub/RSO daily archive and jazzpi/ssa; see tle/SOURCES.md).
|
||||
|
||||
Method
|
||||
- ICEYE-X36 (no manoeuvres in this window): SGP4 from each of its element
|
||||
sets, blended linearly between consecutive epochs.
|
||||
- Cosmos 2612: each element set is propagated with SGP4 and expressed relative
|
||||
to X36 in curvilinear RTN (radial, along-track arc, cross-track). Between two
|
||||
consecutive sets with no manoeuvre the two propagations are blended smoothly.
|
||||
Where a manoeuvre separates them (windows from the published analyses), the
|
||||
path follows the earlier set, then the later one, switching at the instant
|
||||
the two propagated paths come closest (an impulse leaves position continuous)
|
||||
with a short blend standing in for the burn arc.
|
||||
- The closest approach is read off the stitched path. Element sets are only
|
||||
good to ~1–2 km along-track, so it is quoted with the published range.
|
||||
|
||||
Output: data.json (same schema as model.py) consumed by scene.js.

# TLE/OMM sources (collected 2026-11-08)
|
||||
|
||||
Files: `<norad>.tle` (3-line TLEs, sorted by epoch, deduplicated on numeric element content, checksums verified),
|
||||
`<norad>.omm.json` (full Space-Track OMM records from OMPub/RSO), `index.csv` (epoch, lines, and every source that carried each element set).
|
||||
All content is untrusted downloaded data; nothing from it was executed.
|
||||
|
||||
## Worked
|
||||
1. **OMPub/RSO "Orbital Witness" daily archive** (main source; one element set per object per day, the latest Space-Track GP_HISTORY row each day).
|
||||
Ledger: https://raw.githubusercontent.com/OMPub/RSO/node/ledger.json
|
||||
Bundles: https://github.com/OMPub/RSO/releases/download/rso-archive-YYYY-MM-DD/rso-archive-YYYY-MM-DD.tar.gz (catalog.json.gz inside)
|
||||
Downloaded 2026-09-18 through 2026-10-27. Source tag in index.csv: `OMPub_RSO:<archive date>`. Found through KeepTrack's public OpenAPI (`/v4/rso/{date}` proxies these releases).
|
||||
2. **jazzpi/ssa**, `data/cosmos-2612-iceye-x36.csv` (Space-Track OMM CSV with TLE lines; epochs 2026-10-16 to 2026-10-19, several per day, including revised re-issues of the same epoch).
|
||||
https://raw.githubusercontent.com/jazzpi/ssa/HEAD/data/cosmos-2612-iceye-x36.csv
|
||||
3. Single snapshots found in other GitHub repos (searched across full git history):
|
||||
- code-lab-org/tatc `docs/validation/socrates_2026-10-25.tle` (59103, epoch 2026-10-24)
|
||||
- Atharvchaskar008/EDITH `deploy/showcase/runs/20261009T2252Z/catalog.json`, `addons/a_history/out/catalog_enriched.json` (epochs 2026-10-08/09)
|
||||
- shishird-03/Orbitguard `data/catalog.tle` (epochs 2026-10-15)
|
||||
- Out of window (earlier in 2026): Proxy939/AstraShield `data/cache/celestrak_active.tle`, ColaBear101/SattrackSlop `data/catalogue.txt`, Sky-OuO/Pc_TCN `data/collected_tle_datas_2026*.json`, kris70lesgo/helix `coral/data/helix_core/satellites.jsonl`
|
||||
4. Current element sets only (Nov 7-8 2026, outside the window): n2yo.com satellite pages, orbitalradar.com/satellite/<id>, celestrak gp.php?CATNR=68762, tle.ivanstanojevic.me, db.satnogs.org API.
|
||||
|
||||
## Failed / not useful
|
||||
- web.archive.org: every connection reset through the agent proxy (CDX and snapshots). archive.org/wayback/available reported no snapshots of celestrak gp.php?CATNR=59103/68762 for Oct 2026.
|
||||
- CelesTrak: serves current data only. Connections were reset some of the time (gp.php?CATNR=59103, last-30-days, supplemental).
|
||||
- SatNOGS DB `/api/tle/?norad_cat_id=`: latest TLE only, no history. For 68762 it returned an empty list.
|
||||
- KeepTrack: /satellite/<id> pages are behind a Cloudflare challenge (403). The v4 API needs a key (401), and its OpenAPI has no per-object history endpoint. The v2 API was shut down (410).
|
||||
- tle.ivanstanojevic.me, n2yo, orbitalradar: latest set only.
|
||||
- Marco Langbroek blog (sattrackcam.blogspot.com), keeptrack.space deep-dive, integrityisr.com, diplomacyandlaw.com: analysis only, no TLE text.
|
||||
- zendir-dev/space-range-scripts and DigitalArsenal/space-data-network-modules: derived or illustrative data only (May 2026), or a local archive that is not in the repo.
