Settings

The Satellites Settings screen offers some choices.

Normally, the observer's location will be obtained from the location provided by the device, but this can be over-ridden by entering latitude and longitude here.

It is also possible for
Satellites to show an impression of the 'twilight zone,' the band on the Earth within which ISS observation is possible. This may be helpful in estimating the quality of a pass.

Satellites was written to show only the International Space Station. However, from time to time, when a Shuttle flight is launched to visit ISS, Satellites tries to show its location. The Shuttle's orbit is adjusted as it chases the ISS, and again after it departs to return to the ground, and predictions are harder to get right, but Satellites uses the best information available from NASA and won't be far from correct.

In 2009, the Shuttle visited the Hubble Space Telescope to perform a last maintenance mission. Satellites was updated to also show Hubble for that mission, and Hubble has remained available since then. In this version of Satellites, Hubble is not shown by default but can be revealed by changing the settings. There are no predictions for Hubble.

Finally, Satellites will beep once when the observer is centered in the view and ISS is about to rise over the horizon. You have about two minutes to run outside and find a good place to watch from!
