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!

If you are having an issue with any of my apps PLEASE drop me an email at support@vosworx.com. There are a number of people who have left comments about the app not working but have never contacted me about the issue. At this point there are no known issues for the application and it is working as it always has.

Welcome to the Ham Radio specific version of the SatSeries of applications (ProSat, HamSat and ISS). This application provides you access to all of the current amateur radio satellites and 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...)

Check out the Video QuickStart guide at http://www.youtube.com/watch?v=iuPccQI9oSg to see the app in action.

Thanks to everyone who has sent in their questions/requests and keep them coming!

Love the upgrade

Love the new Sat info. Screen with the 15 degree elevation increments. The only problem I have had is a slight delay in position (ie: where the app says the sat is lagging slightly behind actual position) and a rare crash. But since the crashes are so infrequent, I think it may not Have any thing to do with the app. I suggest you enable push messages to warn of upcoming passes. Then I'll give it a 5.

It works!

I just listened to my first amateur radio satellite pass (AO-85) with the help if this app. Without having to use a compass, the app pointed in the right direction, and provides a countdown timer for both AOS and LOS.

Sat data missing

The app does not provide satellite frequencies nor provide Doppler shift information. The frequencies are all zero
