Circumpolar circling satellites are incessantly scanning the earth's surface from several orbits located at a distance from the earth between 200 and 600 kilometre's (LEO) using manifold kinds of measuring instruments. In the satellite, the data is modulated on a short-wave signal and transmitted to the earth. Using an USW antenna (Disconne or Turnstile) and a short-wave receiver, the signals are recorded. A decoder programmed specifically for this task analyses the signal (e.g. the grey shades of an image) and, in real-time, generates a new set of tones. Thus, each data transmission of a circling satellite is translated into tones that last 15 minutes at the most - until the satellite's receiver scope vanishes on the short-wave horizon (elevation) again.
Using the captured satellite signals, Udo Fon, member of the artists group badbeuys is composing a new sonic universe which he resends on air via the radio waves.
