malice 7dc1f9c28e v0.12.0: sat_positions adapter (live global satellite positions) + sat_common refactor 
Adds a new SourceAdapter that publishes the current sub-satellite point
(lon, lat, alt) plus velocity + heading for every tracked NORAD ID every
60s on subject central.sat.position.<norad_id>. Complement to v0.11.1's
satpass_predict (observer-anchored pass alerts): sat_positions is the
GLOBAL counterpart, "where is sat X right now?" rather than "when does
sat X pass over observer Y?". Neither replaces the other.

data_class=telemetry surfaces these on /telemetry, not /events (60s ticks
across ~190 sats would drown discrete-event signal). Severity 1. Geo
centroid = sub-sat point so consumers can plot the satellite directly.

Refactors satpass_predict.py to import its pure SGP4 helpers from a new
sat_common.py module (matches the wfigs_common / swpc_common precedent).
Moved: EARTH_RADIUS_KM, gmst_rad, eci_to_ecef, subsatellite_point (4
symbols, ~25 lines of pure math). Observer-specific helpers stay in
satpass_predict.py. Existing satpass_predict tests pass unchanged.

CENTRAL_SAT stream max_bytes bumped from 1 GiB to 5 GiB to accommodate
the additional ~1.9 GiB/week of position events. STREAM_CATEGORY_DOMAINS
extended from ("tle", "pass") to ("tle", "pass", "position") so the
retention sweep covers position events.

Ships disabled (enabled=false) -- celestrak_tle must be enabled and have
polled at least once for sat_positions to have TLE data to propagate.

README.md

Central

Central is the data hub spine for the infrastructure. Adapters normalize upstream sources into a canonical event shape, publish CloudEvents to NATS/JetStream, and archive to TimescaleDB for historical query. Single-LXC deployment.

Status

Phase 0 — scaffold. Not yet operational.

Architecture

  • Python 3.12 (uv-managed)
  • NATS + JetStream for live event bus
  • TimescaleDB + PostGIS for archive and geospatial query
  • One supervisor process managing adapter lifecycle
  • One archive consumer process persisting events to TimescaleDB
  • Both processes systemd-managed

Testing

See docs/test-database.md for test database setup.
