The WebSDR radio could be operated remotely via the browser through the CAT-Control. To forward the Doppler-shifted reception frequency of the satellite to an amateur radio receiver, a so-called CAT-Control driver for this receiver is needed. It determines the positions of satellites in real-time, whether you want the information at the current time of day or later. "Orbitron" is a satellite tracking system for radio amateurs and satellite observers.

It feeds what it receives on the amateur radio bands live to the Internet and makes it available to all interested listeners via a web page. WebSDR (Web = accessible via the Internet, SDR = Software Defined Radio) is a radio receiver operating in a web browser. This application is developed to track satellite radio signals via WebSDR, taking into account the Doppler shift by using the MyDDE driver of the satellite tracker "Orbitron."

I'm still working on it, waiting for your opinions and bug reports. It's FREE (Cardware) and it's probably one of the easiest and most powerful satellite trackers, according to opinions of thousands of users from all over the world.

It's also used by weather professionals, satellite communication users, astronomers, UFO hobbyist and even astrologers.Application shows the positions of satellites at any given moment (in real or simulated time). Orbitron is a satellite tracking system for radio amateur and observing purposes.
