COMMS ARCHITECTURE

ISL: Satellites relay data between each other — minimal ground stations needed. GROUND: Satellite only communicates when a ground station is in direct view.

ORBIT TYPE

LEO: 160-2000km. MEO: 2000-35786km. GEO: 35786km fixed. SSO: Sun-synchronous. PO: Polar, ~90° incl. VLEO: Under 450km. HEO: Highly elliptical. GTO: Transfer orbit.

ALTITUDE (km)

Height above Earth's surface. LEO: 550km typical. GEO: exactly 35786km.

INCLINATION (°)

Angle of orbit relative to equator. 0°=equatorial, 90°=polar, 98°=SSO.

QUANTITY

LIFETIME (yr)

Expected operational life. LEO: 5-10yr. GEO: 15yr. VLEO: 1-3yr.

SATELLITE NAME

Launching multiple → auto-numbered: NAME-1, NAME-2...

LAUNCH MODE

AUTO: instant deployment, same as before — orbital plane placed at random. MANUAL: pick a real launch site — the satellite's orbital plane is anchored near that site's longitude, and the real-world azimuth needed to reach your chosen inclination is calculated for you.

QOSE RELAY

        Start a Relay session from the Hub account menu → RELAY — that's the one place sessions are created now, so a link's app scope is always set up right. Once one's running, come back here to manage it.

CONJUNCTION RISK

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.

No conjunction alerts

HISTORY MODE

SELECT DATE

View your fleet's orbital positions on a past or future date, propagated using real orbital mechanics (mean motion / Kepler propagation). Earthquake data for the selected date is pulled live from USGS historical records.

OFFSET0 DAYS (NOW)

SESSION EVENT TIMELINE

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

HISTORICAL EARTHQUAKES (USGS)

Select a date and enter history mode to load records.

NOTES

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.
