Browser-based:

Android:

  • Ham Satting – The all-in-one, multi-platform application for amateur radio satellite tracking. Real-time visualization, pass predictions, QSO logging, SSTV decoding, and more—all in one powerful tool.
  • ISS Detector – this is the one I use. It is the most full-featured one I have found. It also puts events in your calendar. $2.99 to track all the ham satellites.
  • Look4Sat – as good as ISS Detector but does not put events in your calendar.
  • ORBIT – this is a hosted open-source browser-based app.

iPhone:

  • GoSatWatch – Well recommended. $9.99
  • Ham Satting – The all-in-one, multi-platform application for amateur radio satellite tracking. Real-time visualization, pass predictions, QSO logging, SSTV decoding, and more—all in one powerful tool.
  • ISS Detector – this is the one I use. It is the most full-featured one I have found. It also puts events in your calendar. $2.99 to track all the ham satellites.
  • ORBIT – this is a hosted open-source browser-based app.
  • PulseSat – Visualize satellites interactively.

Windows:

  • Ham Satting – iOS/macOS/Android/Windows/Linux – The all-in-one, multi-platform application for amateur radio satellite tracking. Real-time visualization, pass predictions, QSO logging, and more—all in one powerful tool.
  • KlaTrack – Windows/Mac/Linux – I LOVE this piece of software! It shows a nice graph where the y-axis is elevation and the x-axis is time. At a glance, you can can see when satellites are passing over and how high above the horizon they will get.
  • SATPC32 – Windows – All in one app to control radios and rotors.
  • SatTrack – Windows – Feature rich application to track satellites and control rotors and radios. The “Future Pass Planner” shows the polar chart of all the future passes.
  • SkyRoof – Windows – Combines satellite tracking and SDR functions in one application.
  • Zenith – (Self-host) A modern web-based satellite tracking application designed for amateur radio operators and satellite enthusiasts. Zenith provides real-time satellite tracking, pass predictions, and radio integration features.

Mac:

  • Ham Satting – iOS/macOS/Android/Windows/Linux – The all-in-one, multi-platform application for amateur radio satellite tracking. Real-time visualization, pass predictions, QSO logging, and more—all in one powerful tool.

Historical Software

Over many years, a wide variety of programs have been developed for use in satellite operations.  Many of these programs are still useful, while others are of historical interest only.  To download many of these programs, as well as other information and files visit https://www.amsat.org/amsat/ftp.
