ProSatHD is the iPad specific version of the ProSat application. The application's UI has been completely re-worked to take full advantage of the iPad's increased screen size.

You can check out a quick overview of the app at http://www.youtube.com/watch?v=tiHCGxV0WM8.

Also, you can download the User's Guide at http://www.vosworx.com/images/docs/SatSeriesHD.pdf.

That said, this application allows access to the following satellite databases from www.celestrak.com.

-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


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...)

Thanks to everyone who has sent in their questions/requests that have led to this application being created.

Keep them coming!

Very nice, but some suggestions

I really like your app. A few suggestions for you:
1. Please let me add satellites from the "what's up" to the "map view/manage" sats tabs! When I am looking to see what satellites I can see in the next hour, I want to be able to add them to the map directly, not have to memorize their sometimes difficult to remember names in order to add them to my managed satellites list.
2. Please let me add more than 10 satellites to my managed lists. Or at least let me make multiple groups of 10 that I could turn on and off depending on what I want to show on the map. The iPad 2 in particular should be able to handle many more than 10 on the map at once.
3. It would be really cool to have the ability to calculate "Iridium Flares" that are coming up at my position. If one has never seen an Iridium Flare, they are quite impressive and well worth the effort of adding to your app.
4. A satellite 3D view with compass and elevation, that would guide you to see the satellite the way "Pocket Universe", "Go Sky Watch", etc. Guide you to find stars in the sky. Hold your iPad up and an arrow could guide you to where the satellite is in the sky. This would be especially useful with the Iridium Flares mentioned above.
5. Maybe a Wikipedia page under the details page about each satellite, if there is such a wiki page. I would love to learn more about the various satellites I am tracking.

Thanks for reading my suggestions.

Useful yet unrefined

I agree with the previous review in that there needs to be an option to add a satellite to my managed list from the "what's up" menu. The app is fantastic and otherwise has a lot of potential for ham radio and astronomy. A few things that could be changed to polish the app would be re-work of the night mode, there is still a lot of white light that comes though. More flexibility in creating groups and organizing satellites.
