VIEWS
When Satellites starts up, it shows a view of the globe of the Earth and the orbit of the International Space Station (ISS) around it. The globe is sized to fit the screen and oriented as if one were viewing it from zero celestial longitude and latitude -- there’s nothing particularly special about that choice, it had to be somewhere. That orientation can be rotated by dragging the globe around with your finger, and the view can be zoomed in and out by ‘pinching’ with two fingers.

The icon buttons at the top right and left of this globe view will reorient the globe to bring either the ISS or the observer to the center of the screen. When it starts up,
Satellites tracks real time -- the view is where the ISS is now. Using the slider at the bottom of the screen, you can change the motion of the Earth and ISS -- you can speed it up to see where the ISS will be in the future; you can reverse and stop the motion. You return to 'now' by double tapping the screen.

ASTRONOMY
You don’t need much astronomical knowledge to enjoy
Satellites, but it can help understand what’s being displayed by the application and some of the terminology used here.

TIME
Satellites displays a slider at the bottom of the screen to 'reverse' or 'fast forward' the clock.
