App Description

ISS Locator uses your current location to determine when the International Space Station will pass over. The iPhone magnetometer is used to indicate which direction to look. The iphone gyroscope is used to indicate the altitude on the horizon where the ISS will appear. A countdown lets you know exactly when the sighting will begin as well as how long it will last. Sightings can added to the calendar or a notification can be set. An email describing the sighting can be sent to a friend.

ISS Locator is a great educational tool and a lot of fun to use.

Note: Location services MUST be enabled for this app to function. Please enable location services for ISS Locator in your Settings app.

Note: Only visible sightings are reported. Visible sightings happen at dawn and dusk. You can not see the ISS or any satellite in daylight or in total darkness.

Note: The Hubble Space Telescope orbit is tilted to the equator at an angle of 28.5 degrees, which means that it never travels farther north than 28.5 degrees N. latitude (the latitude of Cape Canaveral, Florida), or farther south than 28.5 degrees S. latitude (the approximate latitude of Brisbane, Australia).
