SatVis vs Unvigintuple Calc

Satvis is a free, open-source satellite tracker. It draws more than 12,000 satellites on a 3D globe in real time, across fourteen catalog groups: Starlink, GPS and the other navigation constellations, weather and Earth-observation satellites, the ISS and other crewed stations. Set where you are and it works out when each one passes overhead, and your iPhone reminds you before the pass starts. Point your iPhone at the sky to find the ISS, Starlink and 12,000 more satellites overhead. WHAT IT DOES • Follow more than 12,000 satellites live on a 3D globe, with positions computed on your device • Show points, labels, orbits, ground tracks, sensor cones and 3D models, coloured by orbit class • Turn any of the 14 catalog groups on or off, or search for a single satellite • Track a satellite and the camera follows it along its orbit • Set a ground station, list its upcoming passes, and get a notification before one starts • Find a satellite overhead in the sky view, aimed by moving your phone • Choose 3D, 2D or Columbus view, with base maps, star fields, terrain and 3D buildings • Share the exact view you are looking at as a link • Keep using it offline from cached satellite data WHERE THE DATA COMES FROM Orbital elements come from CelesTrak, refreshed every six hours, and are propagated on your device with SGP4.
