Other Pass Prediction Tools

This is a collection of tools to help you know when the next satellite passes are happening.

On the web:

On an Android:

  • 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.
  • Ham Satting – 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.
