Pc(max) is the absolute worst-case collision probability for the miss distance shown, maximized over every possible position uncertainty — not a point estimate from real covariance, which QOSE doesn't have. Treat it as a conservative upper bound, not a forecast.

Close approach alerts between your satellites and tracked objects.

Real geometric union of coverage circles over a 10° lat/lon grid — overlapping satellites are counted once, not double-counted. Assumes an idealized zero-elevation-mask footprint per satellite.

No session events recorded yet — launch satellites to begin tracking.

Select a date and enter history mode to load records.

Satellite positions are mathematically propagated (real Kepler/mean-motion math) from your fleet's current orbital elements — not live-tracked while in history mode. Earthquake records are real historical data from USGS for the selected date.

Real-world upcoming rocket launches worldwide.

Write and format flight scripts with full syntax highlighting. Editing only — this does not execute code inside QOSE (that's planned for a future WASM sandbox).

Pipe real telemetry into satellites you've already launched in QOSE — matched by name. Doesn't create new satellites.

Connects to buckets you own (S3, GCS, Azure Blob, or anything else reachable by URL). Use a pre-signed/SAS URL or your own public endpoint — QOSE holds no credentials of its own. Your bucket's CORS policy must allow this origin. Config here stays in memory for this session only, never saved.

Only needed if your URL isn't already pre-signed/SAS. Sent as-is in the Authorization header on push/pull requests.

Import a real TLE for true SGP4 propagation — not the synthetic circular model. Get free TLEs from your own Space-Track.org account or any TLE you already hold.

Tap a satellite in the Fleet panel to see its orbital elements.

Orange dots = ground stations. Trail shows one full orbital period. Cyan/white dot = current position.
