Where the ISS At?

App · Weather & Space · 7 actions

Track the International Space Station with Where the ISS At?: where it is right now, where it was or will be at any moment, the path it traces over the Earth, the country and timezone it is flying over, and the orbital elements (TLE) pass-prediction tools need. No account or API key required.

Actions

ActionWhat it does
Get a satellite's positionGet where the International Space Station is right now: latitude, longitude, altitude, speed, the size of the area it is over and whether it is in sunlight.
Get orbital elements (TLE)Get the satellite's current two-line element set (the orbital data tracking software needs to predict passes), both as separate fields and as the plain three-line block those tools expect.
Get positions at specific timesGet a satellite's position at up to ten separate moments in one request, for example the times a pass was reported, or the same minute on ten different days.
Get the ground trackFollow the path a satellite traces over the Earth: an evenly spaced run of up to ten positions from a starting time.

Get a satellite's position

Get where the International Space Station is right now: latitude, longitude, altitude, speed, the size of the area it is over and whether it is in sunlight. Pick a time to get where it was, or will be, at that moment instead. No API key required.
