Thales - a successful application of Retsina multi-agent technology, integrates three sources of information to make a prediction of satellite visibility:
  1. Geographical coordinates of the region of observation;
  2. Weather forecast websites for the region of observation;
  3. Passage of visible satellites over the area at the specified time.
