Satellite radio signals are broadcast to earth by powerful transmitters circling in geosynchronous orbit rather than from conventional radio towers on the ground 卫星广播讯号是透过同步卫星上的强力发射器传送到地球上,而非利用地面上的传统广播电塔。
Also spotted by other skywatchers , the mystery cloud was quickly recognized as a fuel dump from a booster rocket used to place a satellite in geosynchronous orbit 这个画面同样被其他天空观测者发现,很快地,这条神秘的云带被认为是用来发射地球同步轨道卫星的助推火箭脱落燃料箱后造成。
In order to cover the whole earth ’ s surface , telecommunication satellites are arranged in two ways : one is to put three geosynchronous satellites at the geosynchronous orbit ( about 35 , 700km altitude ) . another is to put several tens or several hundreds of satellites at low earth orbit ( about 700km altitude ) 为了能够覆盖整个地球表面,通信卫星通常采用两种方式布置:一种是用三颗地球同步轨道卫星( 35 , 700公里) ,另一种是需要几十至几百颗的低轨道( 700公里)卫星。
A geosynchronous orbit (sometimes abbreviated GSO) is an orbit around the Earth with an orbital period of one sidereal day (approximately 23 hours 56 minutes and 4 seconds), matching the Earth's sidereal rotation period.V.
