Satellite radio signals are broadcast to earth by powerful transmitters circling in geosynchronous orbit rather than from conventional radio towers on the ground 衛(wèi)星廣播訊號是透過同步衛(wèi)星上的強力發(fā)射器傳送到地球上,而非利用地面上的傳統(tǒng)廣播電塔。
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 這個畫面同樣被其他天空觀測者發(fā)現(xiàn),很快地,這條神秘的云帶被認為是用來發(fā)射地球同步軌道衛(wèi)星的助推火箭脫落燃料箱后造成。
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 ) 為了能夠覆蓋整個地球表面,通信衛(wèi)星通常采用兩種方式布置:一種是用三顆地球同步軌道衛(wèi)星( 35 , 700公里) ,另一種是需要幾十至幾百顆的低軌道( 700公里)衛(wèi)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.
