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.

HamSat is part of the Sat series of applications (ISS, HamSat and ProSat) and is a visualization/utility application that allows Ham Radio operators wanting to work the amateur ham radio satellites to see the location of the satellites in realtime over the Earth (up to two satellites may be tracked simultaneously).

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

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. Controls are given to allow you to select: the texture maps used, whether shading is performed, whether to draw political boundaries and if a lat/lon grid should be presented.

If you are interested in more than just the Amateur Radio satellites then please take a look at ProSat which has all of the features of HamSat but adds in a little more than 700+ additional satellites.

Thanks for the feedback and keep it coming!

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.

Very different experience...


I actually use both ProSat and HamSat on my iPhone (ProSat for viewing stuff like the Shuttle and ISS and HamSat specifically configured with only the amateur sats that I work. That way I don't have to flip back and forth in setting up the lists of satellites)

That said, I just updated my review of ProSat as my experience was so different than others who have been posting recently so I figured I'd update this one as well (it's much the same as what I put for ProSat). Anyway, I use these apps every few weeks to either wow my friends that I can predict the overflight of the ISS from my phone or to allow me to work a specific satellite from my handheld I've been using these apps for a few years now without issue (actually just used it last night to watch an overflight) However, what had me take the time to write an updated review is that some posts made it sounds like the author wasn't responsive and I had to speak up. I've sent a number of enhancements to the author (that he's included) and he's always been easy to get a hold of (heck he responded at like 10p one time on a weekend) Anyway, just wanted to put in my opinion as my experience has been nothing but good and the apps working fine for me.

Looks good, not necessarily for a beginner


I'm just now starting out in trying to use satellites. I've got a 2m/70cm HT (Icom IC-91AD) and I'd like to use it for Satellite DX. I don't already know which satellites have which modes, and I'm finding myself going back and forth between the AMSAT website to the iPhone trying to find which satellites have which modes and where they are over the globe.

I would like to be able to put in a mode or modes (2m/70cm, 70cm/2m, 2m/2m, etc) and have the app tell me which satellites are above the horizon or will be in the next 30 minutes or something like that. Then I could pick one and give it a shot.

I'm also not sure why I need to put in the frequencies that the sats are using, when they're on the same AMSAT website that the author is probably using to grab the orbital data...Couldn't you put that in the list as well? I'd like this to be my one-stop-shop for what I need away from the desk.
