Satellite Tracker is the follow on to our award winning HamSat series of applications. Satellite Tracker merges all the features of the iPhone and iPad versions providing you a single application that seamlessly optimizes the screen to the device you’re running it on (check out the various iPhone and iPad screen shots).

The application will calculate the rise/set times and associated azimuth and elevation for the selected satellite, Sun or Moon given either the user entered or network retrieved location.

There are two modes for satellite rise/set calculations. The first is for those folks wanting to know all overflights for a given location (like Ham radio operators) while the second mode computes only those passes where the satellite would be visible to a ground observer. In the ground observer mode, the calculations not only take into account that the ground is dark but also that the satellite is in sunlight (it even takes into account if the satellite becomes lit or unlit during the pass)

In addition, you can see the Earth rendered either as a 3D globe or a 2D map using photo realistic texture maps for the Earth model. The orientation of the map is easily changed by a simple rotation of the device from portrait (3D) to landscape (2D). In either orientation you can zoom in and out as well as pan using the touch screen.

There are more than a dozen controls provided to allow you to customize how the application works to meet your specific needs (type of Earth texture used, location, type of overflight calculated…)

Finally, the application is now free to download and provides full functionality for tracking, viewing and communicating with the International Space Station (what was the capability of the ISS family of paid apps). The following subscriptions are available for tracking and communicating with a larger set of satellites:
-HamSat (Annual and Monthly): Provides access to the NORAD and AMSAT two line element sets which cover all amateur related satellites.
-ProSat (Annual and Monthly): Provides access to thousands of satellites grouped into the following categories (from
-100 (or so) Brightest
-Last 30 Day’s Launches (or so)
-Amateur Ham Radio Satellites
-Disaster Monitoring
-Earth Resources
-GPS Operational
-Search & Rescue (SARSAT)
-Space & Earth Science
-Space Station

Good for amateur radio

I’ve been enjoying the app so far. One feature I would like to see is the NORAD ID number listed on the satellite details and an area for making notes on the satellite for things like activation tones and transmit tones. Keep up the good work!

Overall good, ISS uplink/downlink are reversed

Seems like a decent little app although the ISS uplink and downlink frequencies for the cross band repeater are reversed.


Works very well, subscription is worth it

I was also satisfied with the previous version now called classic. It seems the other two reviews have a problem with the developer wanting to be compensated for their efforts. The subscription price is reasonable and it will enable the developer to continue to improve the app over time.

The only reason that I didn’t give the app 5 stars is due to an iOS limitation, not a product limitation. Apple refuses to implement Bluetooth serial in iOS which would be very useful for doppler tuning ham radios.
