At that altitude, air density is 1/10 of what it is at sea level. This significantly decreases the impact of wind on the balloon's position; furthermore, the average wind speed at these levels is less than that at the surface. An ion thruster or electric propeller would allow the balloon to move into and maintain its position. The GBS would be powered with solar panels en route to its location and then receive laser power from a cell tower it hovers over. A GBS could be used to provide broadband Internet access over a large area. Laser broadband would connect the GBS to the network, which could then provide a large area of coverage because of its wider line of sight over the curvature of the earth and unimpeded Fresnel zone.〔(【引用サイトリンク】url=http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=5966806&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D5966806 )〕〔(【引用サイトリンク】url=http://noaasis.noaa.gov/NOAASIS/ml/genlsatl.html )〕 ==See also== * Atmospheric satellite * Geostationary satellite * Internet.org * Project Loon 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Geostationary balloon satellite」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
