iPad Screenshots


Well after a BUNCH of work, I have managed to consolidate all of the SatSeries of apps (ProSat, HamSat, ISS and their iPad cousins) into a single universal application that provides access to different features via a subscription model. The "Classic" versions of the app will continue to be supported for defects through the end of the year but all new feature development will be focused on the new universal application.

So, head over to the new Satellite Tracker application (https://itunes.apple.com/us/app/satellite-tracker/id1438679383?ls=1&mt=8) to keep up on all the new features!

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...)

--- Question & Answer ---

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

Keep them coming!

I was hesitant to pay $10 for an app I knew nothing about but it turns out it was worth every penny. I love telling my friends that the Space Station is going to be flying overhead in 10 minutes and sure enough, there it is. Everybody thinks I'm some sort of NASA wizard. Also, the app on the iPad is pure eye candy. The look of the dark side of the Earth with all the city lights is amazing. It's one of those apps that you pull up for someone when you want to show off the iPad. I have 4 satellite apps ( yea, I'm a geek) and this is by far the best one. I also had a question about something, e-mailed the website received a reply the next day. Get it, you won't be sorry. And "NO", I don't work for the company.

Liking the iPad version

I've been a long time use of the iPhone version of this app so when I saw there was an iPad version I was quick to buy (I've used the heck out of the iPhone version as I backpack a lot and like to look at satellites while I'm out) I REALLY like the new graphics (wow, the Earth blending between night and day is much better)

That said, while I like it I think it could be better. I'd give it five stars if you'd add in a graphical compass view like you see in many of the desktop satellite programs. I'd also like to see Iridium Flare prediction and a 3D version of the viewing. I'm thinking it would be the satellite against the star background from your location using the compass and inclinometers in the iPad so you could steer the iPad and the pic would change (look at StarWalk for an example)

Anyway, way cool app and even better with a few more additions.

Fantastic resource; I'm just getting started

This app provides exactly the information I need, and in great depth. I just ordered a portable radio transceiver, and I'm hoping to listen to the ISS and amateur radio satellites. Now I can easily learn when flyovers are taking place, so I can get the best signals.

I'm sure I'll also enjoy spotting satellites and telescopes like the Hubble. It's hard to believe the amount of information this app provides for ten dollars; I'll be using it for years to come. Don't hesitate; if your search brought you here, you've found what you're looking for!
