If you don’t feel like running to a website every time that you want to know where a satellite is, you can also go mobile.
iPhone users can take advantage of the free Satellite Tracker app, and you can download this app from iTunes. This app tracks apps as they pass over you and your phone. You can input the satellites that you want to track, and the app shows you where these satellites are. You can track as many satellites as you want, and you can add frequency information.
Besides satellites, you can view the current location of the moon and sun. This app is mainly for iPhone users that want to follow amateur radio satellites.
Another app for iPhones and iPod Touches is the GoSatWatch. This app allows you to track satellites, and it even predicts when a satellite is supposed to fly overhead. You can select a satellite from the list and see its current location and predicted path.
You can get notified when a satellite is passing overhead, and you receive all information in real time. You can view information in either portrait or landscape orientation. This app costs $9.99, and you can download it from iTunes.
