ZephyrosSpace processes Two-Line Element sets from NORAD and Space-Track.org every 90 minutes, feeding a custom SGP4 propagator that calculates orbital positions with sub-kilometer accuracy. The prediction engine accounts for atmospheric drag coefficients, solar radiation pressure, and gravitational perturbations from Earth's oblate shape to generate flyover schedules up to 10 days in advance.
The augmented reality module uses device gyroscope and magnetometer data combined with GPS coordinates to overlay satellite trajectories directly onto your camera view. The rendering pipeline displays orbital velocity vectors, altitude readouts, and trajectory arcs in real-time, updating position data every 2 seconds during active tracking sessions.
Space weather monitoring integrates NOAA SWPC data streams for solar wind speed, proton flux density, and Kp-index geomagnetic activity. The alert system triggers push notifications when solar storm conditions exceed user-defined thresholds, with predicted satellite communication disruption windows calculated using ionospheric absorption models.
Access tracking data for 20,847 active satellites including ISS, Starlink constellation, GPS navigation satellites, and classified military spacecraft. Database updates automatically every 90 minutes with fresh TLE data from authoritative sources. Filter by orbit type, launch date, country of origin, or operational status.
Point your device at the sky to see live satellite positions overlaid on camera feed with trajectory prediction arcs extending 15 minutes into the future. Tap any satellite to reveal orbital parameters, velocity vectors, and next visible pass times. Works in daylight and darkness with automatic brightness adjustment.
Calculate visible passes for any satellite from your GPS location with configurable filters for minimum elevation angle, maximum magnitude, and time window. The algorithm accounts for Earth's shadow cone to show only illuminated passes during twilight hours. Export pass schedules to calendar with automated reminders.
Live dashboard displays solar wind speed, proton flux levels, Kp-index geomagnetic activity, and X-ray flux from GOES satellites. Configurable alert thresholds send push notifications when solar storm conditions threaten satellite operations or create aurora viewing opportunities at your latitude.
Compute orbital period, apogee, perigee, inclination, and ground track patterns from TLE data. The decay prediction module estimates atmospheric re-entry dates for low-orbit objects using ballistic coefficient analysis. Visualize Hohmann transfer orbits and delta-v requirements for orbital maneuvers.
Interactive globe displays real-time satellite positions with color-coded orbital paths showing altitude zones. Rotate, zoom, and tilt the Earth model to examine specific orbital planes. Time acceleration mode lets you preview satellite movements hours or days ahead at speeds up to 1000x real-time.
