Satvis vs Seen from Space

Satvis is a free, open-source satellite tracker for iPhone and iPad. It draws more than 16,000 satellites on a 3D globe in real time: Starlink, GPS, weather satellites, the ISS and many more. Set your location and it predicts when each one passes overhead. The sky view shows the sky from where you stand. Point your phone up to see the satellites in that direction. WHAT IT DOES • Visualize satellites on a 3D globe in real time, propagated on the device with SGP4 from CelesTrak's element sets • Show points, labels, orbits, orbit tracks, ground tracks, sensor cones, 3D models and ground station links per satellite, colored by orbit class (LEO, MEO, GEO, HEO) • Switch catalog groups on and off (Starlink, GNSS, weather, Earth observation, crewed stations), or search for a single satellite • Select a satellite to see its orbit, its next passes over your locations and its spacecraft details: country, operator, manufacturer, bus, mass and size • Track a satellite: the camera flies to it and follows it along its orbit • Save your location or any point you pick on the map, then list the upcoming passes over it and get a notification before one starts • Find satellites overhead in the ground-level sky view, aimed by dragging or by pointing your phone, with the camera's picture of the sky behind them • See which satellites you could spot: the sky view dims those in Earth's shadow, too far away or in a daylit sky • View the globe in 3D or flattened to 2D, over the base map, star field and terrain you choose: satellite imagery, Earth at night or the day's VIIRS imagery • Start from the featured views, bookmark your own, and share any view as a link: it opens the same view on satvis.space • Open satvis.space links straight in the app • Keep using it offline, from the satellite data it last fetched WHERE THE DATA COMES FROM Element sets come from CelesTrak, refreshed several times a day, and are propagated on your device with SGP4. Spacecraft details come from Jonathan McDowell's GCAT. FREE AND OPEN SOURCE No account, no ads, no in-app purchases. Developed in the open at github.com/Flowm/satvis under the MIT license.

Know what changed at your place. Google and Apple maps show a satellite picture that is one to three years old. Seen from Space shows you a fresh Sentinel-2 image of any point on Earth every few days, tells you the moment a new one is published, and puts two dates side by side so the change is obvious. SEE IT FRESH • A new 10 m satellite image of your point every 3 to 5 days, worldwide, from the European Sentinel-2 mission • Alerts when a new image of your point is published (free) • Know in advance when the next satellite passes and whether it will image your point SEE IT SHARP (United States) • 0.6 m aerial photos (0.3 m in newer flights) for any US address: houses, cars, trees, driveways • Year-by-year history back to 2010, flip through the years over the same spot • Compare an aerial photo with this week's satellite image SEE WHAT CHANGED • Before / after with a draggable divider • Timelapse of your point as a video or GIF, ready to share • Vegetation view: see where plants are growing or drying out, and the trend over the season • Share a one-page PDF report of any comparison FOR Land owners, farmers and gardeners · home buyers and sellers · builders and site managers · people watching a place they care about, wherever it is. Seen from Space Pro adds: all aerial years, 30 days of image history, compare any two dates, vegetation trends and change maps, a 15 km view, alerts before a satellite passes, all commercial and radar satellites, unlimited points, and exports without the wordmark. Monthly, yearly, or once. Imagery: Copernicus Sentinel-2 (ESA), USDA NAIP aerial photography via Microsoft Planetary Computer and USGS. Orbit data: CelesTrak, through the public mirror tle.ivanstanojevic.me. Predictions are computed on your phone; your points never leave it except as the area of the image you request. Contains modified Copernicus Sentinel data 2026. Seen from Space is independent and not affiliated with ESA, NASA, USGS or any satellite operator.
