International Space Station

By Tension Software

Open the Mac App Store to buy and download apps.


International Space Station allows to see the position of the the International Space Station over an interactive map of the world.
With a simple view of the map you will be able to see if the International Space station will be visible from your local position in the next hours.

With a simple click you can also see the live webcam stream coming from the International Space Station. You will watch the astronauts activities with video and audio, all live.

Calculation of the position of the station is very accurate, the app uses the latest NASA code optimized for Mac to calculate it. You don't get an approximated position, you get the exact position, speed and altitude of the Station.
The route path is visualized over the map to evaluate if the station is coming near your position in the next hours (when meteorological and light condition are adequate you can see it without any instruments, just observing the sky naked-eye)
You can zoom, move and resize the map as you like at any time.

The app downloads at regular time, once per day when you startup it, from our server, the latest orbital parameters to calculate the orbit, so the calculation obtained for the position is always accurate and perfect because the app uses updated orbital parameters.
No user action required, the app does it all.
Our own server provides always updated NASA data to your app when it requires it.

International Space Station is easy and fun to use, anyone can use it even if it uses sophisticated satellite orbit calculation with the same alghoritm used by pro orbital calculation software.

Requires OS X
• Perfect results as using pro orbital software but in an easy to use app
• Customizable latitude/longitude format
• Measure units in Km and Km/h or NM and MPH
• Zoomable Map
• 'Keep Centered' function
• Includes a PDF User Guide

Plus it offers fast access via your web browser to various dedicated area:

• Page Station at NASA
• Web Cam stream on board of the station
• Audio stream from the station
• Facebook page of the station
• Twitter presence
• YouTube presence
• Flickr presence

Requires an internet connection for map visualization, data update once a day, web cam stream and web pages access.
Position calculation is performed locally using the latest algorithm for orbit computation coded for Mac OS X
We have also a version for the iPhone and the iPad . Search on iTunes for 'ISS Track'

Money back if you don't like this app!

App Store release of this app is fully functional, included automatic update of keplerian elements to calculate perfect orbit tracking. When we say in the manual that our update function is not included in the App Store release, we mean that you get updated releases via the App Store as for any other apps in the store. Just that.
So we repeat it again: App Store releases of International Space Station is fully functional at 100 % included automatic update of keplerian elements day by day and bugs of the release 1.0 are now fixed in the current release.
(International Space Station is on the App Store only)

Customer Reviews


I think the app is worth the small price. Its operation is intuitive, and I have had no difficulty using it. An obvious improvement would be to show the terminator line/area between daylight and darkness. If this is too involved, showing the current position of the sun would accomplish much the same purpose.
