Satellites is an iPhone/iTouch/iPad application that displays the location of the International Space Station (ISS) as it orbits the Earth. The data used is downloaded from up-to-date NORAD and NASA sources so it is as current as it can be. The algorithms used for the orbit predictions are also current, being the latest revisions of the NORAD three-line element SGP software republished in 2006.
The application shows the location of the ISS, the 'footprint' within which the ISS is above the horizon, and one orbit of the upcoming ground track over the ground (solid in sunshine, dotted in shadow).
The application will show the location of the observer's device on the earth. The globe of the earth can be rotated and zoomed by touches and pinches to get a detailed view of, for example, when ISS passes near the observer.
Time can be "speeded up" with a slider to see where the ISS will be at times in the not-too-distant future (the predictive data and algorithms do not claim high accuracy after a few days).
There is also a list of times when the ISS is predicted to pass within view of the observer in the next few days. Some passes will be in daylight and not visible; those before dawn and after sunset are usually visible.
More features are planned -- your input is valued.

Great app. Thanks
I really like this app. It shows the ISS circling the globe, and you can speed it forward or backward in time as well as at the present moment. Fascinating. Shows the total earth night and day and you can spin it anywhere you like. It will locate where you are or the ISS is or anywhere and alerts you to when the station can be seen by you and in the future. Great. I wanted to know more about it, emailed Ramsey and Gavin got right back to me and was more than helpful. Excellent. Thank you, john
Best ISS tracker app available.
I've had this app almost a year and I use it all the time. It's easy to use, and understand. You can visually see the orbit and its footprint. I love the function of fast forward to see future orbits. Just wish you could populate a date instead of just fast forward. Regardless, this is an awesome app, don't pass it up. 5 stars!
Interface a bit clunky
All in all a good app. Shows the position of the ISS and Hubble.
Maps are wireframe, but adequate. A sat view would be superb.
The interface is somewhat "clunky" but I'm sure the dev has plans to improve over time. A good purchase in my opinion.
