The application "WebSDR Cat-Control" now establishes a connection from Orbitron to the WebSDR receiver via the MyDDE-Driver and forwards the Doppler-shifted reception-frequency of the satellite to be tracked in real-time. DDE allows programs to manipulate objects provided by other programs and respond to user actions affecting those objects. In computing, DDE or Dynamic Data Exchange is a technology for interprocess communication used in early versions of Microsoft Windows and OS/2. This driver transmits the receive frequency via DDE. Orbitron provides a driver called MyDDE for this purpose. 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." ![]()
