This program is written for Android system. It is at the moment the fastest and in my opinion the most advanced satellite tracker for this platform.
Apart from the graphics and interface, SatTrack uses the latest algorithms to precisely calculate the position of satellites. It also has the fastest search engine for flying above satellites. This program can easily handle 5000 satellites at once in real time. SatTrack can calculate uplink and downlink in radio communication. This program is constantly being improved and new functions are added. Version 1.0 is now available as apk from the site.
