In this website you can track in real time all the known satellites orbiting the Earth, with both 2D and 3D interactive representations, predict their passes, view their trajectory among stars on an interactive sky chart, predict satellite flares and transits (across the Sun and the Moon), find out the best location to see these events on a detailed Google map. You can also watch realtime video with overlays from HD cameras onboard the ISS, follow satellite re-entries and other special events, join the observer community, post messages and share your comments and observations. Currently in our database we have more than 9000 observation reports!. Registered users can now even have a personal agenda with an audio guide who assists them to spot the satellites and flares at the right time. This site is not just a tracker! You won’t find any other website that provides all these functions! Enjoy!
