A tracked civil or military aircraft's trail (`src/data/trailContinuity.js`) lifts
|
||||
the pen, drawing nothing, between two points more than 48 minutes or over 1,500 kt
|
||||
apart (a parked aircraft within 0.1 nm keeps one line for up to three hours) and at a
|
||||
waypoint with no altitude; a ground waypoint is drawn on the ground. The head joins the
|
||||
aircraft only within 150 km. Each trail keeps up to 2,000 points, a full day of history
|
||||
at one fix per minute plus the live session; past that the oldest recorded points go
|
||||
first, and the oldest reports only once none are left. The renderer
|
||||
(`src/data/trailRenderer.js`) freezes every chunk of 128 points except the newest into
|
||||
static geometry, so a long trail costs about as much per frame as a short one;
|
||||
`scripts/qa-trail-freeze.mjs` checks that a freeze never shows a blank frame.
|
||||
While an aircraft is tracked, its trail between reports is the path its icon was
|
||||
drawn along: the displayed position is recorded about once a second or every 150 m
|
||||
(`recordTrailPoint`). Recorded points are thinned by shape: one stays only where
|
||||
dropping it would move the line more than 30 m across the track or in height from any
|
||||
position it stood for, or leave a straight piece longer than 10 km, so straight flight
|
||||
adds a vertex every 10 km at most and a turn keeps its curve. A recorded point that
|
||||
would turn the line back sharper than 120° over a short step is dropped. Reports stay
|
||||
in the trail as anchors, in time order. Recorded points never join two reports that are
|
||||
not one flight under the 48-minute and 1,500 kt rules; the points between them go and
|
||||
nothing is recorded across such a pair. A report for a time the display has already
|
||||
passed replaces what was drawn after it, and nothing is recorded until the icon has
|
||||
eased onto it, so the line reads arc, report, corrected path. History from before tracking started, and the backfill, run report to report.
|
||||
The trail never runs past the icon or through its 3D model, and the head runs from the
|
||||
newest kept point outside the model to the icon (to the model's tail when the model is
|
||||
the visual). A contact with no new report coasts along its reported track for 5 minutes
|
||||
past its last real report, at no more than 1,500 kt and never below known ground, then stops;
|
||||
one that
|
||||
went quiet on the ground, or within 150 m of a known ground floor, holds at its last
|
||||
report, records nothing and draws no head (with the ground unknown, a low barometric
|
||||
altitude alone does not hold it). The hold-or-coast choice is made once per report (`staleHoldsForFix`
|
||||
in `src/data/motionModel.js`), and the forward fix built when a repeated position carries
|
||||
new speed or course follows the same rules and is never a trail report. A live report
|
||||
with no altitude breaks the line and leaves no point at an invented height, and so does
|
||||
such a report seeded from position history when tracking starts.
|
||||
|
||||
A contact that misses an update is stale from the first miss: it is drawn with the
|
||||
45%-alpha stale fade (`STALE_ALPHA`), the tracked billboard and 3D model included, and the
|
||||
tracked label reads STALE. For the tracked aircraft a poll that re-sends a fix no newer
|
||||
than the last one is a miss too. Once its coast has ended, or it holds at its last report
|
||||
after a miss, it stands still, dimmed, and the label reads SIGNAL LOST · <time since its
|
||||
last report>, in seconds under a minute and minutes after (`_trackedStaleCue` in each
|
||||
flight layer's `tracking.js`). The tracked aircraft is kept, so the follow camera keeps its
|
||||
target, until 10 minutes after its newest fix (`TRACKED_RETENTION_MS`): 5 minutes coasting,
|
||||
then 5 stopped as SIGNAL LOST. Untracked aircraft keep their missed-poll limits. A report
|
||||
that arrives later eases the aircraft onto it.

The CCTV catalog includes Taiwan national freeway cameras from the Freeway Bureau, MOTC. The app first reads the daily MOTC 2.0 CCTV.xml table with a keyless HTTPS request, a 15-second deadline, a 6 MiB response cap, and the shared 15-minute cache. If that catalog is unreachable and no last-good source list exists, the loader uses the Highway Bureau’s public provincial-road CCTV XML feed at https://cctv-maintain.thb.gov.tw/opendataCCTVs.xml. The fallback is capped by the same Taiwan source limit and hourly retry backoff; its MJPEG feeds are restricted to the eight cctv-ss01 through cctv-ss08.thb.gov.tw HTTPS servers. The frame proxy returns one bounded JPEG from each stream, not an unbounded video response. The Highway Bureau open-data page states XML downloads are free and asks users to attribute the source; the app credits Highway Bureau, MOTC. These are provincial-road cameras, not a replacement for the national freeway cameras. CCTV_TAIWAN_ENABLED=0 disables both feeds; CCTV_TAIWAN_MAX_SOURCES sets the shared cap (default 600, bounded to 1–2000), and CCTV_TAIWAN_URL overrides the Freeway Bureau table URL.

- **Flights (commercial + military)** render one poll interval behind real time (30s/15s) and interpolate between two known feed-stamped fixes (OpenSky `time_position`; adsb.lol `receipt − seen_pos`). The display latency is an intentional product decision — do not "fix" it away. The fleet dead-reckons at ~12Hz (1m² write gating); a contact already hidden behind the horizon whose last position still is re-reckons on a staggered one-in-13-ticks rotation (about once a second) instead, so the worldwide feed's ~13k contacts no longer cost a full pass when well under 1% are on screen. Anything that position puts in view, and any contact with a fleet model, takes the full pass immediately, and hidden-inclusive proximity queries read positions at most about a second old; aircraft get a 3-poll grace period (faded icon) before removal. When a position epoch pauses, both layers coast for at least 60 seconds of contact grace with an absolute five-minute ceiling. Source backoff marks each contact and the cockpit `STALE`; the cockpit then holds the exact layer position instead of continuing inertial flight. Repeated-position kinematic changes create a forward-only synthetic fix rather than mutating history, and grounded history is lifted only when no owned 3D model already controls its datum. A nominally successful worldwide OpenSky response whose own snapshot epoch is more than two minutes old prefers the existing 250-nm viewport-scoped adsb.lol fallback and labels the source/coverage accordingly when that upstream is available. If the fallback is also unavailable, the layer's freshness/error fields use the source epoch—never the cache receipt time—so the UI reports an old snapshot rather than “just now.”

When a position epoch pauses, both layers coast for five minutes on the last speed and heading (at most 1,500 kt), then stop dimmed as SIGNAL LOST; contacts on or near known ground hold instead. Source backoff marks each contact and the cockpit `STALE`; the cockpit then holds the exact layer position instead of continuing inertial flight. Repeated-position kinematic changes create a forward-only synthetic fix rather than mutating history, and grounded history is lifted only when no owned 3D model already controls its datum.

- **World-space headings at every angle** (`src/data/iconOrientation.js`): aircraft/vessel icon rotation uses the camera right/up basis per tick (alignedAxis always ZERO), which is exact at screen center and for orthographic/nadir views and remains stable through >180° tracked orbits. Perspective rays vary across the viewport, so off-center contacts at oblique pitch can diverge from an exact finite-difference window projection; a regression test pins that known regime, and field evidence decides whether to adopt exact projection with the basis method as fallback. Fleet rotations refresh on camera-pose change; tracked entities per frame. Billboards are horizon-culled via a shared EllipsoidalOccluder.
|
||||
- **Military/OpenSky reconciliation** (`src/data/militaryRegistry.js`): known-military ICAOs render amber in the flights layer (60s self-poll of the cached mil endpoint when the military layer is off) and are suppressed there while the military layer renders them.
|
||||
- **Satellites**: core catalog from CelesTrak's stations, visual, GPS, GLONASS, Galileo, GEO, resource, weather, planet, SAR and science groups, tracking lands ~726km out via `viewFrom` (tracked entity owns a point graphic so the tracking camera engages), rings realign via primitive modelMatrix (no per-second rebuild flicker), optional `setParams({catalog:'dense'})` Starlink mode.
