Hi all, Last year I wrote an app to help me operate LEO satellites and in December I decided to make it available in the Google Play Store. The app has information on the satellites I've found interesting, including the radio transponders and beacons on board, in addition to the Keps, that I fetch automatically on occasion over the Internet.

In order to plan activity, the app will show a list of passes coming up for your QTH in the next 18 hours. Once you select a bird you are interested in you will get an Overview Page for it. From there you can select a link taking you to a web page about it, you can also see its Location in real time and its trajectory for the next hour. All passes for this satellite for the next 48 hours are also available from the Overview Page.

From the overview page you can also select Status Reports, that will

display a list based on the Status API that I helped Joe KM1P to set up earlier this week.

Finally if you select a Beacon or Transponder from the overview page you will land on the Aiming View that uses the built in sensors of the phone to point at where in the sky the satellite is in real-time. This view also shows the Uplink and Downlink frequencies with the Doppler shift included. I use this view with my phone mounted on a tripod behind the reflectors on my Arrow beam in portable operations.

I would really appreciate any and all feedback on the app and thanks for making this hobby even more interesting.
