我国研制的新一代通信卫星“东方红三号”于5月12日零时17分由新型的“长征三号甲”运载火箭在西昌卫星发射中心发射升空.24分钟后,卫星进入近地点2O9千米,远地点36194千米的地球同步转移轨道.在西安卫星测控中心控制下,星上远地点发动机作了三次点火,变轨成功,使卫星顺利进入准同步轨道,并已最终将卫星定点在距地球35786千米高度的东经125度赤道上空.“长征三号甲”运载火箭是我国自行研制的地球同步轨道运载能力较大的运载火箭,这种型号
A new generation of communications satellite developed by our country, “Dongfanghong 3”, was launched at Xichang Satellite Launch Center by a new “Long March III A” launch vehicle at 0:17 on May 12. After 24 minutes, the satellite entered the vicinity of 2o9 Km, apogee 36194 km of geostationary transfer orbit.In Xi’an satellite monitoring and control center under the control of the satellite apogee engine made three ignition, orbit change, the satellite successfully into the orbit, and the satellite has been eventually fixed at a distance of The altitude of 35786 kilometers above the Earth’s longitude 125 degrees above the equator. “Long March III A” launch vehicle is our own research and development of geosynchronous orbit carrying capacity larger rocket, this model
