Eyes Above is a free Chrome extension for getting real-time data about the satellites above you. With Eyes Above you can monitor the satellites overhead at this very moment, as well as their past and current positions in space.

You can see how many satellites are currently operating above you, as well as what country they belong to, and the approximate altitude, in thousands of kilometers above the earth's surface.

With Eyes Above you can also keep a closer eye on the location of satellites currently in orbit and those that are due to launch into space in the next few years. The app includes an experimental sonification using FM synthesis and LFOs to create an acoustic corollary to the data it displays.
