Слайд 5


S-BAND (2–4 GHZ) WEATHER RADAR, SURFACE SHIP RADAR, AND SOME COMMUNICATIONS SATELLITES, ESPECIALLY THOSE OF NASA FOR COMMUNICATION WITH ISS AND SPACE SHUTTLE. IN MAY 2009, INMARSAT AND SOLARIS MOBILE (A JOINT VENTURE BETWEEN EUTELSAT AND ASTRA) WERE AWARDED EACH A 2×15 MHZ PORTION OF THE S-BAND BY THE EUROPEAN COMMISSION.
