Replace geocentric.distance().km - 6371 (fixed spherical radius) with
wgs84.subpoint(geocentric).elevation.km in the /position endpoint.
The SSE tracker was already fixed in the Task 1 commit.
Previously currentPos only had lat/lon, so the updateTelemetry fallback
(used before first live position arrives) always showed '---' for
altitude/elevation/azimuth/distance. currentPos now includes all fields
computed from the request observer location. updateTelemetry simplified
to delegate to applyTelemetryPosition.
TLE data was only refreshed once at startup. After each refresh, a new
24-hour timer is now scheduled in a finally block so it fires even on
refresh failure. threading moved to module-level import.
SSE runs server-wide with DEFAULT_LAT/LON defaults of 0,0. Emitting
elevation/azimuth/distance/visible from the tracker produced wrong
values (always visible:False) that overwrote correct data from the
per-client HTTP poll every second.
The HTTP poll (/satellite/position) owns all observer-relative data.
SSE now only emits lat/lon/altitude/groundTrack. Also removes the
unused DEFAULT_LATITUDE/DEFAULT_LONGITUDE import.
- Add --no-cache-dir and --timeout 120 to all pip calls to prevent hanging
on corrupt/stale pip HTTP cache (cachecontrol .pyc issue)
- Replace silent python -c import verification with pip show to avoid
import-time side effects hanging the installer
- Switch optional packages to --only-binary :all: to skip source compilation
on Python versions without pre-built wheels (prevents gevent/numpy hangs)
- Warn early when Python 3.13+ is detected that some packages may be skipped
- Add ground track caching with 30-minute TTL to satellite route
- Add live satellite position tracker background thread via SSE fanout
- Add satellite_predict, satellite_telemetry, and satnogs utilities

- Fix SSE fanout thread AttributeError when source queue is None during
interpreter shutdown by snapshotting to local variable with null guard
- Fix branded "i" logo rendering oversized on first page load (FOUC) by
adding inline width/height to SVG elements across 10 templates
- Bump version to 2.26.0 in config.py, pyproject.toml, and CHANGELOG.md

ensureModeScript() used document.body.appendChild() to load lazy mode
scripts, but the preload for ?mode= query params runs in <head> before
<body> exists, causing all deep-linked modes to silently fail.
Also fix cross-mode handoffs (BT→BT Locate, WiFi→WiFi Locate,
Spy Stations→Waterfall) that assumed target module was already loaded.

SSE EventSource connections for AIS, ACARS, VDL2, and radiosonde were
not closed when switching modes, causing fd exhaustion after repeated
switches. Also fixes socket leaks on exception paths in AIS/ADS-B
stream parsers, closes subprocess pipes in safe_terminate/cleanup, and
caches skyfield timescale at module level to avoid per-request fd churn.
Closes#169

METEOR-M2-4 was defined as an active weather satellite but had no
orbital data, so pass predictions always returned empty. Added TLE
entry and CelesTrak name mapping for automatic refresh.

When dashboards (satellite, ADS-B, AIS) are loaded via iframe with
?embedded=true, the full navigation bar was still rendered, creating
a "UI in UI" effect. Pass the embedded query param from route handlers
to templates and conditionally skip the nav include.
Fixes#144

Satellites added via CelesTrak import or TLE paste are now stored in
SQLite and survive page reloads and app restarts. Adds CRUD API
endpoints and wires frontend sidebar + dashboard to use them.

Security: replace path traversal-vulnerable str().startswith() with
is_relative_to(), anchor path checks to app root, strip filesystem
paths from error responses, add decoder-level path validation.
Architecture: use safe_terminate/register_process for subprocess
lifecycle, replace custom SSE generator with sse_stream(), use
centralized validate_* functions, remove unused app.py declarations.
Bugs: add thread-safe singleton locks, protect _images list across
threads, move blocking process.wait() to async daemon thread, fix
timezone handling for tz-aware datetimes, use full path for image
deduplication, guard TLE auto-refresh during tests, validate
scheduler parameters to avoid 500 errors.
Docker: pin SatDump to v1.2.2 and slowrx to ca6d7012, document
INTERCEPT_IMAGE fallback pattern.

Open Notify API (api.open-notify.org) is frequently unreliable,
causing 5-second timeout delays on every ISS position request.
Promote wheretheiss.at as the primary API in both satellite.py
and sstv.py, demoting Open Notify to fallback.

- Add refresh_tle_data() function for reusable TLE updates
- Automatically fetch fresh TLE from CelesTrak when app starts
- Runs in background thread to avoid slowing down startup
- Includes NOAA-20 and NOAA-21 in name mappings
- Gracefully handles failures (uses cached data if offline)
- Existing /update-tle endpoint now uses shared function
This ensures satellite tracking data is always fresh, fixing
inaccurate positions caused by stale TLE data.

- Add _fetch_iss_realtime() helper function for real-time ISS position
- Satellite position endpoint now uses real-time API for ISS specifically
- Other satellites still use TLE-based calculations
- ISS orbit track still calculated from TLE (for future/past positions)
- Falls back between Open Notify and Where The ISS At APIs
This ensures the satellite dashboard shows accurate ISS position
while maintaining TLE-based tracking for other satellites.
