In these page can be found descriptions of satellites signals, some help with satellite tracking techniques and some analyses of individual satellites. Originally, most satellite tracking was done by ear with a little help from a pen recorder. Nowadays, sound is almost the last thing with a majority of information being extracted from a computer display or a spreadsheet.

Satellite tracking is only possible by knowing where in the radio spectrum to listen. From the menu on the right it is possible to useful lists of frequencies. As launches occur, new satellites appear in orbit that can be tracked. Sometimes the launch vehicle can be tracked in its own right.

Satellite and launch vehicle series tend to use frequencies repetitively. To see what might be coming up, there is the Zarya events calendar - Go For Launch!.
