SatTrack tells you when the ISS and other bright satellites will pass over your site.
Key features
• Next-pass time, max elevation, and direction at a glance
• Sky-path plot of the pass across your local sky
• Visual-pass filter: you in darkness, satellite still sunlit
• Save observer sites and get a reminder before the next visible pass
• Pick your site by coordinates, current location, or map
Predictions use public two-line element sets and the SGP4/SDP4 propagator. Refresh the catalog when a connection is available; accuracy drops as the elements age.
