P-Track Satellites Viewer

Explore Earth, ISS & Orbits

Free · In‑App Purchases

Explore satellites on iPhone and iPad, follow passes on Apple Watch, inspect spacecraft in 3D, and check optional cloud forecasts before your next pass. Your world. From orbit. Follow the ISS and Tiangong around an interactive 3D Earth. Find upcoming satellite passes, explore the sky above you, and take a closer look at spacecraft, the Sun and the Moon. START WITH THE SPACE STATIONS Track ISS and Tiangong for free. See their orbital tracks and coverage footprints, find your observing location, and open flight details for altitude, speed, range and elevation. Catalog information is free to browse. KNOW WHEN AND WHERE TO LOOK See upcoming overhead passes and separate estimates of naked-eye visibility. Use Sky View's radar and expandable satellite list, or open the camera-optional Sky Finder for direction and tilt guidance. Pass mode shows a countdown and where to look. Above the horizon does not necessarily mean visible to the eye. PASS REMINDERS AND CLOUD FORECASTS Enable reminders for supported satellites at saved observing places. New basic reminders cover overhead passes, including daylight and low passes, 15 minutes before predicted rise. Optional cloud forecasts from MET Norway describe conditions near the predicted pass peak. Weather is an estimate and never cancels a pass reminder. Alerts are scheduled locally; open P-Track regularly to extend coverage. iOS controls notification delivery and background refresh. EXPLORE EARTH, SPACECRAFT, SUN AND MOON Rotate and zoom the globe, inspect a larger spacecraft model, and open information about supported components. Read dimensions, mass and other available satellite facts with source links. Explore the Sun and Moon with familiar rotation and zoom controls, then return to Earth. Spacecraft illustrations and models are representative artwork, not engineering drawings or live configuration telemetry. SEE THE IONOSPHERE Explore global vertical total electron content using CODE maps from the Astronomical Institute, University of Bern. Forecast and analysis maps are labeled with their valid times. Adjust opacity, inspect contours, and learn what electron content means through the interactive guide. Missing or stale data is identified. ON iPHONE, iPAD AND APPLE WATCH Use the larger globe and adaptable radar/list layout on iPad. The Apple Watch companion shows pass countdowns, north-up direction guidance, available cloud forecasts and reminder controls from your paired iPhone. Watch data depends on iPhone synchronization; it is not an independent satellite predictor or compass. Widgets and Live Activities are available on supported devices. P-TRACK PRO ISS and Tiangong observing, basic reminders at one editable place, and station widgets are free. Pro adds tracking and observing for supported GPS, Starlink and Other satellites, additional saved places, custom reminder windows and numerical brightness filters. Monthly and six-month auto-renewable plans provide the same Pro access. Prices and billing periods appear before purchase. Restore Purchases is available in the app. Subscriptions renew automatically unless canceled in your Apple account settings. Satellite availability and forecast coverage depend on the data feeds. Positions, passes, brightness and weather are estimates for education and exploration, not navigation or safety-critical use. Optional location, camera and notification permissions support the corresponding features. Camera frames are not recorded or uploaded by P-Track.
