目前,“中星Ⅴ号”卫星传送着中央一台、中央二台、中央三台、浙江台、新疆台和西藏台等8套电视节日。“中星Ⅴ号”卫星是1984年6月10日发射的,设计寿命10年,因此,估计我国不久将重新发射“东方红Ⅲ号”卫星。届时,“中星Ⅴ号”及“亚洲Ⅰ号“卫星上的电视节目均将改由“东方红Ⅲ号”卫星传送。 现在,我国有几十万座小型卫星电视接收站,其天线大部分为手动二维调节天线。换星时,方位角和高度角都要相应改变。卫星接收站所在地理位置不同,所需调整的方位角和高度角也各异。一般情况下需由专业人员来完成换星工作。在我国
At present, “Zhongxing V” satellite transmits 8 sets of television festivals such as Central One, Central Two, Central Three, Zhejiang, Xinjiang and Taiwan. The satellite “V” was launched on June 10, 1984 and has a design life of 10 years. Therefore, it is estimated that China will re-launch the “Dongfanghong III” satellite soon. At that time, the television programs on “V-Star V” and “I-Asia” will be transmitted by “Dongfanghong III” satellite. At present, there are hundreds of thousands of small satellite television receiving stations in our country, and most of the antennas are manually two-dimensionally adjusted antennas. Change star, the azimuth and elevation angle must be changed accordingly. Satellite receiving station where the geographical location, the required adjustment of the azimuth and elevation angle are also different. Under normal circumstances need to be replaced by professionals to change jobs. In my country
