List of satellite pass predictors

Ground track example from Heavens-Above. An observer in Sicily can see the International Space Station when it enters the circle at 9:26 p.m. The observer would see a bright object appear in the northwest, which would move across the sky to a point almost overhead, where it disappears from view, in the space of three minutes.

The following is a list of tools on a variety of platforms that may be used to predict the pass of an orbiting artificial satellite over a given point on Earth. They are used to generate a list of dates, times and directions when and where objects such as the International Space Station, Genesis, or Tiangong 1 space stations will be visible to ground observers, as well as many man-made objects that can be seen with the unaided eye including the Hubble Space Telescope.

Raw orbital data

All websites and applications base their predictions on formula using two-line element sets which describe the satellites and their orbits.
